A solid cone of b

Answer :

Let the height of the cone be H m

Radius of the frustum = R = 10 cm

After cutting, the new height of the cone = m

Let the new radius of the cone be r cm

r = = 5 cm [ the cut has been made at the midpoint of the cone]

Volume of the new cone = πr2h


Volume of the frustum =




Ratio of the two volumes =

= 1: 7
