Answer :

Given,

Radius of cylinder = 12 cm

Height = 20 cm

Before drop a ball volume of water = v1 = πr2h = πr2 × 20 cm3

After droping rise in water level = 6.75 cm

New height = 20 + 6.75 = 26.75 cm

New volume = πr2 × 26.75 cm3

Volume of spherical ball = πr2 (26.75 – 20)

= πr2 × 6.75 = cm3

= πR3 = 3054.85

= R3 = = R = Rate this question :
