Question

Find the surface area of a cylinder with a height of 8 in and a base diameter of 8 in.

Answer 1

Surface Area of A Cylinder

301.44 square inch

Explanation:

Surface Area of a cylinder = 2πrh + 2πr²

Given Height h = 8 in

Given Base diameter d = 8 in

So the base radius r =
`(d)/(2)`

r =
`(8)/(2)` = 4

Curved Area = 2πrh = 2 × 3.14 × 4 × 8 = 200.96

Total Surface Area (SA)= 2πrh + 2πr²

SA = 2 ×3.14 × 4 × 8 + 2 × 3.14 × 4 × 4

SA = 200.96 + 100.48

SA = 301.44 square inch
