A+30 = 60
a = 30
a + 2b = 60
30+2b = 60
2b = 30
b = 15
5b - 5c = 60
5(15) - 5c = 60
5c = 15
c = 3
10c + d = 60
10(3) + d = 60
30 + d = 60
d = 30
2d + 6e = 180 - 60
2(30) + 6e = 120
6e = 60
e = 10
4f + 4e = 120
4f + 4(10) = 120
4f = 80
f = 20

Answer:
The answer to this question is A
Answer:
The answer is 256 
.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V = 
. However, in this formula, 3 will be used instead of (
).
Next, plug in the information given from the problem, and the formula will look like V = 
(3) (
).
Then, solve the equation, and the answer will be 256 .
