Given the volume of the cylinder is v=39 in^3

We will use the formula of the cylinder volume to solve.

We know that:

V = r^2 *pi * h such that v is the volume, r is the radius, and h is the height.

We are given the volume and the height.

Then we will substitute into the equation.

==> 39 = r^2*pi * 12

Now we will divide by 12.

==> r^2 *pi = 39/12 = 3.25

But we know that the area of the base is given by :

A = r^2 * pi

**Then, the area of the base of the cylinder is 3.25 in^2**
