Question

Use the formula SA = 2πrh + 2πr2 to find is the surface area of the cylindrical food storage container. Use 3.14 for π. Round your answer to the nearest hundredth of a square inch.

A cylinder. The radius of the base is 8 inches and the height of the cylinder is 11 inches.

Answer 1

Explanation:

SA = 2πrh + 2πr²

where;

π = 3.14

r = 8

h = 11

Slotting in those parameters, we have;

= (2 x 3 x 8 x 11) + ( 2 x 3 x 8²)

= 528 + 384

= 912 inches²

To the nearest 100th, answer becomes 900inches²
