Question

What happens to the volume of a sphere when its diameter is doubled?

Answer 1

Consider this solution:
1) formula of volume is   $V= \frac{4}{3} \pi r^3, where \ r - radius$
2) if new_r=2r, then the formula is   $new_V= \frac{4}{3}*(2r)^3= \frac{4}{3} \pi *8r^3=8*( \frac{4}{3} \pi r^3)$
3) new_V/V=8:1
The volume increases by 8 times.

Answer 2

Answer:

Its volume is 8 times greater.
