The volume of the cylinder is 3148 yd cube. What is it's radius?

volume = π x r^2 x h

where:

π is Pi, approximately 3.142

r is the radius of the circular end of the cylinder

h height of the cylinder;

Then, 3148 = 3.142 x r^2 x h;

r^2 x h = 1001.909;

We don't know h.

So, we couldn't find r.
