Step-by-step explanation:
The answer should be 8.5 I think
Answer:
3 in
Step-by-step explanation:
The volume of the large sphere is ...
V = (4/3)πr³ = 288π . . . cubic inches
The volume of the smaller sphere is ...
288π -252π = 36π . . . cubic inches
The ratio of volumes of the smaller sphere to the larger is the cube of the ratio of radii. The radius of the smaller sphere will be ...
(6 in)∛(36π/(288π)) = (6 in)∛(1/8) = 3 in . . . . small sphere radius
The perimeter is the sum of the side-lengths, which we're given! We don't know the value of a, but we can find the perimeter in terms of a by adding up the side-lengths:
So our answer is
.
