Answer:
96π cm²
Step-by-step explanation:
Use the formula for the surface area of a cylinder:
A = 2πrh + 2πr²
Plug in the height and radius, and solve:
A = 2π(4)(8) + 2π(4)²
A = 2π(32) + 2π(16)
A = 64π + 32π
A = 96π
So, the surface area of the cylinder is 96π cm²

It's not specific enough, I'll come back to you!
Answer:
62.6%
Step-by-step explanation:
To convert the mountain height to miles, we divide its height in feet by the number of feet per mile. We want the fraction of that represented by 3 miles, so ...
(3 mi)/((25,289 ft)/(5,280 ft/mi)) × 100%
= 3(5280)/25289 × 100% ≈ 62.6%
If you climbed 62.6% of the mountain's height, you would be 3 miles above sea level.
Let's say p = 3
2(3)^0
Solving that, you'd get 2
C is the only answer that does not equal one
