Answer 2

Surface area of a cylinder

The surface area of the cylinder is 219.8 square ft

Step-by-step explanation:

The surface area of a cylinder is defined as the sum of the curved surface are and twice the area of the flat surface

SA = 2πrh + 2πr²

Given Height h = 2 ft

Given Base radius r = 5 ft

Curved Area = 2πrh = 2 × 3.14 × 5 × 2 = 62.8 sq ft

Total Surface Area (SA)=  2πrh + 2πr²

SA = 2 ×3.14 × 5 × 2 + 2 × 3.14 × 5 × 5

SA = 62.8 + 157

SA = 219.8 square ft

Hence the surface area of the cylinder is 219.8 square ft
