A drinking glass is in the shape of a frustum of a cone of height 14 cm. The diameter of its two circular ends are 16 cm and 12 cm. Find the capacity of the glass.
Given: Height of glass = h = 14 cm
Diameter of lower circular end of glass = 12 cm
Diameter of upper circular end of glass = 16 cm
∴ Radius of lower circular end = r = 12/2 = 6 cm
∴ Radius of lower circular end = R = 16/2 = 8 cm
= 44 × 49.33 cm3
2170.52 cm3
∴ Capacity of glass = 2170.52 cm3
