What is the total surface area of the cylinder?

113.04 in. 2

100.48 in. 2

131.88 in?

69.08 in

Answer: 112.04 in2

Option A = 113.04in^2

Step-by-step explanation:

Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.

A) 113.04 in. 2

B) 100.48 in. 2

C) 131.88 in. 2

D) 69.08 in. 2

Solution:

Total surface area of a cylinder = 2πr^2 + 2πrh

r = radius = 2in

h = height = 7in

Let π = 3.14

Total surface area of the cylinder =

2*π*2^2 + 2*π*2*7

= 8π + π*28

= 8*3.14 + 3.14*28

Total surface area of the cylinder = 113.04in^2

=113.04in^2 (option A)
