well suppose that there was a volcano "frustum of cone shape" caved from inside "the cave funnel is cylindric shape"

r1 :- is the radius of base of the fustum = 50 m

r2 :- is the radius of top of the frustum = 25 m

r3 :- is the radius of funnel "cylinder" = 10 m

h :- is the height for both of frustum and cylinder = 100 m

find the volcano volume

remember :- the volcano is frustum caved by cylindric shape "i mean in this question"

also :the cylinder is inside frustum

i dont think it is really difficult

good luck mathematica

bye
