Question

The diameter of a circle is 12 ft. Find its area to the nearest whole number. Answer: A = ​

Answer 1

Area = 113 ft²

Explanation:

The formula to find the area of a circle is:

Area = π × r²

r is the radius that can be found by taking half of the diameter.

r =
`(12)/(2)` = 6

Area = π × 6²

Area = π × 36

Area = 113.09 = 113 [ to the nearest whole number ]

Answer 2

113 ft²

Explanation:

π = 3.14
r = 6

Use the formula for the area of a circle:
A = πr²
A = 3.14*6²
A = 3.14*36
A = 113.04
A = 113
Hope this helps :)
