Question

What is the area of a circle whose radius is 5 ft? 5π ft² 10π ft² 20π ft² 25π ft²

Answer 1

25π ft² (just took the quiz)

Answer 2

The area of the circle is equal to
`25 \pi\ ft^(2)`

Explanation:

we know that

The area of circle is equal to

`A=\pi r^(2)`

where

r is the radius of the circle

In this problem we have

`r=5\ ft`

substitute

`A=\pi (5^(2))=25 \pi\ ft^(2)`
