Question

The radius of a circle is 5 inches. What is the area of the circle?

Answer 1

Area of circle with radius `5` inches is
`color(white)("XXXX")` `= 25pi` or approximately `78.54` square inches.

Explanation:

General formula for the Area of a circle with radius `r` is
`color(white)("XXXX")` `A(r) = pir^2`

In this case:
`color(white)("XXXX")` `A(5) = pi5^2 = pi*25 or 25pi`

`pi` is approximately `3.1416`
