Given, h=14cm,r1=3cm,r2=9cm Volume of the frustum =13πh(r12+r22+r1r2) Therefore, volume of frustum =13×227×14(9+81+27) =13×22×2×117 =1716 cm3
Volume of water = volume of frustum = 1716 cm3
A frustum of height 14 cm and radii 3 cm and 9 cm is filled with water upto the brim. Find the quantity of water in the frustum.
