Question 871015: I can't figure this out! Marianne has a mound of snow in her driveway. The mound is in the shape of a cone with a diameter of 4 feet and a height of h feet. Marianne makes spherical snowballs with a radius of r feet from the snow. Which expression could be used to determine the maximum number of snowballs Marianne can make from the snow in the mound?
A.h/r²
B.h/r³
C.2h/r²
D.4h/r³

You can put this solution on YOUR website!
V+cone+=+%281%2F3%29pir%5E2h
d=4 so r=2
V=+%281%2F3%29pi%2A%282%5E2%29%2Ah
V= 2hpi/3
V+sphere+=+%284%2F3%29pi%5Er%5E2
number of snow balls = Volume of cone/volumeof ball
=h/r^2
