I'm not asking for the answer (I hate when people do that) I'd just like to know how to go about this so that I may understand. Any help is much appreciated.
"A sphere of ice cream is placed onto your ice cream cone. Both have a diameter of __ cm. The height of your cone is __ cm.If you push the ice cream into the cone, will all of it fit?"
The sphere with a diameter of r (=(d/2) has a volume of Vs=4πr³/3.
The volume of a cone with a radius of r and height h is Vc=(1/3)πr²h.
If Vs>Vc, the ice cream will not fit in the cone.
