Bore 10, find the base area.

Well, look, we have the diameter itself, which means we have a radius, since it is equal to half the diameter, that is, 10 divided by 2 – this will be 5. And at the base of the cylinder there is always a circle whose area is pi * (radius squared) … And it will be pi * 5 * 5 = 25 * pi. Here is our answer: the base area is 25 * pi.
