Question

10. If the radius of a circle is 40 inches, what is the area of the circle? *

Answer 1

The formular for the area of a circle is as follows;

`area = \pi {r}^(2)`

r » radius, r is 40 in

[taking π to be 3.14]

substitute:

`area = (3.14) * ( {40)}^(2) \\ \\ { \boxed{ \boxed{area = 5024 \: \: in {}^(2) }}}`
