A cone is 14cm deep and the base radius is 41/2cm. Calculate the volume of water that is exactly half the volume of the cone.[Take π = 22/7]
49.5cm3
99cm3
148.5cm3
297cm3
445.5cm3
Correct answer is C
Volume of a cone = 13πr2h
r = 412 cm; h = 14 cm
Volume of cone = 13×227×92×92×14
= 297 cm3
When half- filled, the volume of the water = 2972=148.5cm3
