Answer:
D. 220,781.25 cm3
Step-by-step explanation:
Answer:
The volume of the larger ball would be 221,000
Step-by-step explanation:
In order to find this we first need to find the diameter of the new ball, we can do this by using a proportion.
15/11 = x/55
55*15 = 11* x
825 = 11x
75 = x
Now we take half of that for the diameter and then use that in the volume formula.
V = 4/3(pi)r^3
V = 4/3(pi)(37.5)^3
V = 221,000
