Question 273860
a cylinder with a radius r and height h is topped by a cone whose height is the same as that of the cylinder.
which formula can be used to find the volume of the composite solid?
:
Vol of cylinder: {{{V = pi*r^2*h}}}
Vol of a cone: {{{V = (1/3)pi*r^2*h}}} 
:
Since h and r are the same, add one to 1/3:
V = {{{(4/3)*pi*r^2*h}}}
