# how do i find the surface area of a cylinder with a radius of 3.5 ft. and a height of 14 ft.

The formula for the surface area of a cylinder is: 2πrh + 2πr^2 If we substitute in the measurements that we know, you get: 2$\pi$ (3.5) (14) + 2$\pi$ (3.5)^2 If we simplify this expression, we get: 98$\pi$ + 24.5$\pi$ If you simplify once more, you get 122.5$\pi$ or ≈ 384.85 Therefore, the surface area is 122.5$\pi$ or about 384.85
