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[latex] \pi [/latex] (3.5) (14) + 2[latex] \pi [/latex] (3.5)^2 If we simplify this expression, we get: 98[latex] \pi [/latex] + 24.5[latex] \pi [/latex] If you simplify once more, you get 122.5[latex] \pi [/latex] or ≈ 384.85 Therefore, the surface area is 122.5[latex] \pi [/latex] or about 384.85
