Question

Tommy has a stack of 8 pancakes. Each pancake has a radius of 9

centimeters. What is the area of each pancake?

Answer 1

254.47
`cm^2`

Explanation:

First you have to know the formula for the area of a circle which is:

`A=\pi r^2`

In the word problem it gives us the radius of a pancake which is 9 cm, so we just need to plug it into r in our formula:

`A=\pi r^2`

`A=\pi (9)^2`

`A` ≈ 254.47
`cm^2`
