Answer:
radius = 3 feet
Step-by-step explanation:
V = 1/3πr²h
15π = 1/3πr²·5
you can divide each side by 5π to get:
3 = r²/3
r² = 9
r = 
which is 3

Answer:
8:9

Answer:
4.d.
Step-by-step explanation:
Please see attachment
y = k/x
We want to find k first.
4 = k/8
4(8) = (k/8)(8)
32 = k
We now need to find y knowing that k = 32 and x = 2.
y = k/x
y = 32/2
y = 16
