Question

Find the surface area of the cylinder to the nearest tenth. Use 3.14 for n

A. 1,695 in^2
B. 791.3 in^2
C.565.2 in^2
D.1,985.0 in^2

Answer 1

Remember: The formula for surface area for cylinders are S= 2πrh + 2πr²
The 2πr² represents the circular parts of the cylinder.

First, let's find the lateral side of the cylinder.
→ 2 (3.14)(6)(15) = 565.2
Next, find the circular parts.
→ 2 (3.14)(6²)
→ 2 (3.14)(36) = 226.08
Add the two answers together.
→565.2 + 226.08 = 791.28
Round.
Your final answer is 791.3 in²
I hope this helps.
