Answer 1

Answer: 112.04 in2

Step-by-step explanation:

Answer 2

Answer:

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)
