What is the surface area of the cylinder? Use 3.14 for pi and round your answer to the nearest hundredth.

Answers

Answer:

Surface area of the cylinder = 954.56 inches

Step-by-step explanation:

Given that

π = 3.14

height of the cylinder = 11in

radius of the cylinder = 8in

surface area of the cylinder = ?

recall that,

surface area of the cylinder = 2πrh + 2πr²

surface area of the cylinder = 2 x 3.14 x 11 x 8 + 2 x 3.14 x 8²

surface area of the cylinder = 552.64 + 6.28 x 64

surface area of the cylinder = 552.64 + 401.92
