Question

a cylinder has a radius of 10 and height of 10 what is the surface area

Answer 1

The surface area equation of a cylinder is:

2 * pi * r^2 + 2 * pi * r * h

Plug the values in:

2 * pi * 10^2 + 2 * pi * 10 * 10 is about 1256.64 units squared.

Answer 2

The answer is approximately 1256.64
