Question

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

Answer 1

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
