Question

The radius of a circle is 17 feet. Using the formula A = r2, what is the area of the circle? Use 3.14 for pi.

Answer 1

replace "r" with 17. replace "pi" with 3.14. then calculate

A = pi * r^2

Answer 2

Payton: It's important that you write the equation for the aera of a circle of radius r as A= pi r^2 or \[A=\pi r^2\]

Answer 3

r2 just doesn't cut it in math.

Your formula does not include pi. The correct formula for the area of a circle of radius r is
\[A= \pi r^2\]
