What is the surface area of a cylinder with a base radius 4 and height 5? Either give an exact answer in terms of π or use 3.14 for π.

Solution:

Given, base radius of a cylinder = 4 units

Height = 5 units

We have to find the surface area of a cylinder.

Surface area of a cylinder = 2(area of base) + area of the sides

Area of base = πr²

= (3.14)(4)²

= (3.14)(16)

= 50.24 square units.

Area of sides = 2πrh

= 2(3.14)(4)(5)

= 40(3.14)

= 125.6

Surface area = 2(50.24) + 125.6

= 100.48 + 125.6

= 226.08 square units.

Therefore, the surface area of the cylinder = 226.08 square units.
