Question

Calculate the area of a circle with a radius of 9 inches.

Answer 1

254.47

Explanation:

The formula for area of a circle:

area =
`\pi r^(2)`

where r is the radius.

area =
`\pi 9^(2)`

area = 81
`\pi`

area = 254.469004941

Your professor/teacher didn't specify what to round to - - -

So if you round this to the hundredths place, it would be 254.47.
