Question

What is the surface area of the cylinder 

224 pi ft^2
273 pi ft^2
126 pi ft^2
175 pi ft^2

Answer 1

224π

Explanation:

2πrh+2π
`r^(2)` is the formula for finding the surface area of a cylinder.

14 ft is the diameter, so 7 ft would be the radius (r).

9 ft is the height (h).

Substitute in your values. 2π x 7 x 9 + 2π
`7^(2)` = 703.717 or 224π
