MEDAL & FAN ANYBODY ?
If the radius of a sphere is tripled, then its volume will increase 27 times.
True
False

sleepyjess · Answer

lets test it out
say our radius of the first sphere is 5 second sphere is 15

sleepyjess · Answer

since we just did one with a radius of 5 we know that the volume of r=5 is 523.3333333....
now use 15 for r
$\dfrac{4}{3}\pi 15^3$

@sleepyjess i got 14130 if i was doing it right...

sleepyjess · Answer

$15^3=3375\3375*\pi=10597.5\10597.5*(4/3)=14129.999999=14130$
so now do 523.3333*27 to see if it is equal
523.3333333*27=14129.9999999=14130
