Question

Find the surface area of the cylinder. Give answers in terms of .

11
8
Surface Area = ?
units²

Answer 1

The surface area of a cylinder is given by the formula 2πrh + 2πr². Here, r is the radius and h is the height. So, with r=8 and h=11, the surface area would be 2π*8*11 + 2π*8². That simplifies to 176π + 128π, which is 304π units².
