Question

Find the area of the circle d=10 in 62.80 in^2 ,15.70^2, 314.00in ^2, 78.50in^2, 31.40 in2

Answer 1

Explanation:

In order to find the area, we need to find the radius. In order to find the radius, we need to divide 10 by 2 because the radius is half of the diameter.

10 ÷ 2 = 5

`A=r^2\pi`

`A=(5)^2\pi`

`A=25\pi`

`A=78.5`

So, the area of the circle (given that the diameter is 10) is 78.50 in².
