Question

Find the total surface area of a cylinder with a height of 5 cm and radius of 2 cm. Leave your answer in terms of π.

Answer 1

Answer:

A.28π cm2

Area of a cylinder formula

A=2*pi*r*h+2*pi*r^2

Answer 2

Answer:

The total surface area of a cylinder is $28\pi \ cm^2$.

Step-by-step explanation:

We have,

Height of a cylinder, h = 5 cm

Radius of a cylinder, r = 2 cm

It is required to find the total surface of a cylinder. The formula of the total surface area of cylinder is given by:

$A=2\pi r h+2\pi r^2\\\\A=2\pi r (r+h)\\\\A=2\pi \times 2 (2+5)\\\\A=28\pi \ cm^2$

So, the total surface area of a cylinder is $28\pi \ cm^2$. Hence, the correct option is (A).
