Question

A homeowner wants to build a circular patio. if the diameter of the patio is 20 feet, what is its area to the nearest whole number? 1,257 square feet 314 square feet

Answer 1

Answer: 314

Step-by-step explanation:

1. 49 pic square ft

2. 168 units

3. (4-
`\pi`)ft^2

4. 314square ft

5. 22.6 square mm

6. 12 inches

7. 12
`\pi ft^2`

8. 28.125
`\pi` square centimeters

9. 22.1 cm

10. (243pi+162) ft^2

Just took the practice this will get you a 100 Hope this helps

Answer 2

We are asked to find the area of patio. It is circular so formula used for area is given by:

`A= r^(2) \pi`
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet


`A = 10^(2) \pi =100 \pi`
When we round this to the nearest whole number:

`A =100 \pi = 314.159=314ft^(2)`
