Question 288695: A hemisphere has a radius of 2 cm. Whats the volume of the hemisphere in terms of pi?
I got the actual answer but dont understand how to put it in terms of pi. Heres what i did:
V=4/3*pi*(2*2*2)= 33.5101230666667
and then simplified that to: 33.51
i cut that i half so that id have a hemisphere instead of a sphere: 33.51/2= 16.755
