Find the surface area of a cylinder with a base diameter of 4 in and a height of 3 in . Write your answer in terms of π , and be sure to include the correct unit.

Respuesta :

.

Find Radius:

Radius = Diameter ÷ 2

Radius = 4 ÷ 2 = 2 in

.

Find Surface Area:

Surface Area = 2πr² + 2πrh

Surface Area = 2π(2)² + 2π(2)(3)

Surface Area = 8π + 12π

Surface Area = 20π in²

.

Answer: 20π in²
