What is the base area of the cone?

Step-by-step explanation:

In order to find the area of the circle base, we need the radius, and we don't have it. We'll use the volume to find the radius, as follows:

and fill in the givens:

and solve that for r;

so

r = 3.784698783 and plug that in for the radius to find the area of the circle base:

so

gives you that

A = 45 meters squared, exactly. No decimal.
