Find the area and perimeter of each composite figure use 3.14 for pi round your answer to the nearest 10th
Find the surface area and volume of each figure use 3.14 for pi round your answer to nearest 10th
I have examples if needed
1. Perimeter is 3 + 3 +3 +4 +5 = 18 feet
Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet
2. perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters
Area = 3*.5 = 1.5, 3*2=6, 6+1.5 = 7.5 square meters
3. perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches
Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 52.3 inches
4. surface area = 2*π*6*20+2*π*6^2= 980.2 yards
Volume = π*6^2*20 = 2261.9 cubic yards
5.surface area = 2*(9*7+2*2+2*9) = 190 cm
Volume = 2*7*9 = 126 cubic cm
6. surface area = 2*(11*11+11*11+11*11) = 726 mm
Volume = 11 *11*11 = 1331 cubic cm
1. Area = 15 square feet
2. Area = 5.5 square meters
3. Area = 52.26 square inches
4. Surface area = 312π square yards, Volume = 720π cubic yards
5. Surface area = 127 square cm, Volume = 126 cubic cm
6. Surface area = 726 square mm, Volume = 1331 cubic mm
let's go through each problem step by step with proper calculations:
**Problem 1:**
Given:
Perimeter = 3 + 3 + 3 + 4 + 5 = 18 feet
Area calculations:
- For the triangle: Area = 1/2 × base × height = 1/2 × 3 × 4 = 6 square feet
- For the rectangle: Area = length × width = 3 × 3 = 9 square feet
Total Area = 6 + 9 = 15 square feet
**Problem 2:**
Given:
Perimeter = 2.5 + 2.5 + 2.5 + 2.5 + 0.5 + 0.5 = 11 meters
Area calculations:
- For the triangle: Area = 1/2 × base × height = 1/2 × 0.5 × 2 = 0.5 square meters
- For the rectangle: Area = length × width = 2.5 × 2 = 5 square meters
Total Area = 0.5 + 5 = 5.5 square meters
**Problem 3:**
Given:
Perimeter = 3.14 × 2 × 3 + 8 = 18.84 + 8 = 26.84 inches
Area calculations:
- For the rectangle: Area = length × width = 6 × 4 = 24 square inches
- For the circle: Area = π × radius² = 3.14 × 3² = 28.26 square inches
Total Area = 24 + 28.26 = 52.26 square inches
**Problem 4:**
Given:
Surface area calculations:
- For the cylinder:
- Lateral Surface Area = 2 × π × radius × height = 2 × π × 6 × 20 = 240π square yards
- Top and bottom circles: Area = 2 × π × 6² = 72π square yards
Total Surface Area = 240π + 72π = 312π square yards
Volume calculations:
- Volume = π × radius² × height = π × 6² × 20 = 720π cubic yards
**Problem 5:**
Given:
Surface area calculations:
- For the rectangular box:
- Front and back: 9 × 7 = 63 square cm
- Sides: 2 × (2 × 9) = 36 square cm
- Top and bottom: 2 × (2 × 7) = 28 square cm
Total Surface Area = 63 + 36 + 28 = 127 square cm
Volume calculations:
- Volume = length × width × height = 9 × 7 × 2 = 126 cubic cm
**Problem 6:**
Given:
Surface area calculations:
- For the cube:
- All faces are identical: 6 × (11 × 11) = 726 square mm
Volume calculations:
- Volume = side³ = 11³ = 1331 cubic mm

The circumference of a circle is 28 \pi inches, what is the length of the radius of this circle?
Answer: 14 inches
Step-by-step explanation:
We know that the circumference of a circle is given by :_
[tex]\text{Circumference}=2\pi r[/tex], where r is the radius of the circle.
Given : The circumference of a circle [tex]=28\pi\text{ inches}[/tex]
Then , the circumference of the circle is given by :-
[tex]28\pi=2\pi r\\\\\Rightarrow\ r=\dfrac{28}{2}=14[/tex]
Hence, the radius of circle = 14 inches.

Dominic is a landscape architect and is designing a garden with an area of up to 500 square feet. He will use two types of plants: zinnias and petunias. Each zinnia plant requires 1.6 square feet of ground and each petunia plant requires 1.8 square feet of ground. Each zinnia plant costs $4 and each petunia plant costs $3, and the architect must spend no more than $600.
Let z represent the number of zinnia plants and p represent the number of petunia plants.
Three of the constraints for this situation are z≥0 , p≥0 , and 1.6z+1.8p≤500 .
What is the other constraint for this situation?
Enter your answer in the boxes.
__ z + __ p ≤ __
The third constraint was based on the total area that the garden can only take. Now the last constraint must be based on the total cost that should be spend in order to make a 500 square feet of garden, that is:
4 z + 3 p ≤ 600

A school had an election where the candidates received votes in the ratio of 1:2:3. If the winning candidate received 210 votes, how many people voted in the election?
The number of people who voted in the election is 420 people
Based on the information given,
Winning candidate = 210 votes
Second candidate = 2 × 210/3 = 140 votes
Last candidate = 1 × 210/3 = 70 votes.
The number of people who voted in the election will be the addition of the total votes and this will be:
= 210 + 140 + 70
= 420 votes
Therefore, from the information given, the number of people who voted in the election is 420 people.

A circle with center (3,5) intersects the y-axis are(0,1). find the radius of the circle, find the coordinates of the other point of intersection with the y-axis. what are the coordinates of the point of intersection of the circle and the x-axis
The coordinates of the other point of intersection with the y-axis will be (0, 9). And the x-intercept is at (3, 0).
What is the equation of circle?Let r be the radius of the circle and the location of the center of the circle be (h, k).
Then the equation of the circle is given as,
(x - h)² + (y - k)² = r²
A circle with center (3,5).
Then the equation of the circle will be
(x - 3)² + (y - 5)² = r²
The circle intersects the y-axis at (0,1).
Then the radius of the circle will be
(0- 3)² + (1 - 5)² = r²
9 + 16 = r²
r² = 25
r = 5
Then the equation of the circle will be
(x - 3)² + (y - 5)² = 5²
Then the other y-intercept of the circle (0, a) will be
(0 - 3)² + (a - 5)² = 5²
9 + (a - 5)² = 25
(a - 5)² = 16
a - 5 = 4
a = 9
The intersection of the circle with x-axis at (b, 0) will be
(b - 3)² + (0 - 5)² = 5²
25 + (b - 3)² = 25
(b - 3)² = 0
b - 3 = 0
b = 3
Thus, the coordinates of the other point of intersection with the y-axis will be (0, 9). And the x-intercept is at (3, 0).
The graph is given below.

A quadratic equation is shown below: x2 − 8x 13 = 0 which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers?
a. subtract 5 from both sides of the equation
b. subtract 3 from both sides of the equation
c. add 5 to both sides of the equation
d. add 3 to both sides of the equation
Add 3 to both sides, so you will have
x^2 - 8x + 13 + 3 = 3
x^2 -8x + 16 = 3
And now the left side is a perfect square trinolmial: (x-4)^2.
