Question

Evangeline is buying a circular shaped rug that covers 78.5 square feet. How far is it from one edge of the rug to the other?

Answer 1

Hey there!

In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14).

First, we need to undo the area and find the radius.

78.5/3.14=25

√25=5

Since the diameter is twice the radius, we multiply or radius by two.

5*2=10

Therefore, our edge is 10 feet from one edge to the other.

I hope this helps!
