Answer:
h = 6
Step-by-step explanation:
πr²h = 384π
Divide by pi on both sides.
r²h = 384
8²h = 384
64h = 384
Divide by 64 on both sides to isolate h.
h = 6
Usually the easiest way to solve this is by using a calculator. Of course only if your teacher allows you too.
6/8 can be simplified to 3/4. Therefore the answer is C. 20 X 3/4
A = L^2
A = L^2 = 2^2 + 4^2 (Pythagorean’s theorem)
A = L^2 = 20
Therefore the area of the square is 20 units square.
