Question

A cylinder has a radius of 6 inches and a height of 15 inches. what is the surface area of the cylinder ? express the answer in terms of pie.​

Answer 1

252pi (B)

Explanation:

Find the area of the bases (2 * pi * r^2)

r = 6, so:

72pi = total area of bases

Find the area of the side (pi * 2 * r * h)

r = 6 and 15 = h, so:

180 pi = area of the side

180pi + 72pi = 252pi (B)
