Answer:
B
Step-by-step explanation:
I'm pretty sure it is B but if not I'm sorry
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.
Answer:
x/10 = -9
Step-by-step explanation:
You are given the equation: x = -90
You are asked to divide 10 from both sides. Simplify:
(x)/10 = (-90)/10
x/10 = -90/10
x/10 = -9
x/10 = -9 is your answer.

Answer:
W = 3 feet
L = 14 feet
Step-by-step explanation:
P = 2L + 2W
L = W + 11
34 = 2×(W+11) + 2W
34 = 2W + 22 + 2W
34 - 22 = 4W
4W = 12
W = 3 feet
L = 14 feet
