Question

A right cylinder has a radius of 12 units and a height of 15 units. What is the total surface area, in units squared?

Answer 1

2034.72 units²

Explanation:

Formula for surface area of a cylinder is:

2πrh + 2πr²

The radius is 12 and the height is 15, so we plug it in:

2π(12·15) + 2π(12)²

2π(12·15) + 2π(12)²=2034.72.
