Question

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

Answer 1

Answer:

254.47 $cm^2$

Step-by-step 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 $cm^2$
