Question

Find the surface area of a cylinder with diameter of 10 and height of 4

Answer 1

282.74

Explanation:

Answer 2

282.78

Explanation:

radius = diameter / 2 = 10/2 = 5

Surface area:

A=2πrh+2πr^2

A=(2 * 3.142 * 5 * 4) + (2 * 3.142 * (5)^2)

A=125.68 + (2 * 3.142 * 25)

A=125.68 + 157.1

A=282.78
