Question

The radius of the base of a cylinder is 4.00 in. The height of the cylinder is 12.00 in. Find the surface area of the cylinder using 3.14 as a value for pi. Round to the nearest hundredth.

Answer 1

the surface area is just the sum of the two ends and the curved side.

a = 2πr^2 + 2πrh = 2π*4*(4+12)

Now just evaluate that on your calculator.

Answer 2
