Hello!

To solve this you use the equation to find the surface area of a cylinder


SA = 2 \pi rh + 2 \pi r^(2)

SA is surface area
r is radius
h is height

Put in the values you know and 3.14 for pi

SA = 2 * 3.14 * 5 * 29 + 2 * 3.14 * 5^2

SA = 1067.6

The answer is A)1,067.6ft squared

Hope this helps!
