Ex 13.7 , 1 Assume π = 22/7 , unless stated otherwise. Find the volume of the right circular cone with radius 6 cm, height 7 cm Here, r = 6 cm and h = 7 cm Volume of the come = 1/3 πr2h = (1/3×22/7×6×6×7) cm3 = (1×22×2×6×1) cm3 = 264 cm3 Ex 13.7 , 1 Assume π = 22/7 , unless stated otherwise. Find the volume of the right circular cone with (ii) radius 3.5 cm, height 12 cm Here, r = 3.5 cm and h = 12 cm Volume of the cone = 1/3 πr2h = 1/3×22/7×3.5×3.5×12 cm3 = 1×22/7×35/10×35/10×4 cm3 = 1×22×5/10×35/10×4 cm3 = 154 cm3
