Let the radius of base be r.

Let the height of cone = H

Height of cylinder, h = 3cm

Area of base, A = 100 sq. cm

As we know the area of circle is πr2

πr2 = 100 ….. (1)

Volume of complete solid figure,V = Volume of cone + volume of cylinder

It is given that volume of solid figure, V = 500 cubic cm

On substituting the value of V and πr2 from eq (1), we get,

H = 6 cm

Total height of figure = h + H = 3 + 6 = 9 cm

total height is 9 cm
