Question

A trampoline has an area of 49pi square feet. What is the diameter of
the trampoline?

Answer 1

The diameter is 14π

Explanation:

We know the area of a circle is πr^2

let 49π=πr^2

Cancel the π's, and you get 49=r^2

Take the square root and you get r=7

The diameter of a circle is 2πr.

2π(7)=14π.
