Question

find the amount of water displaced by spherical ball of diameter 3.5 cm when it is completely immersed in water

Answer 1

Diameter of Spherical ball = 3.5

Radius = D/2 = 3.5/2 =1.75cm

AMOUNT OF WATER DISPLACED BY SPHERICAL BALL = VOLUME OF SPHERICAL BALL = 4/3πR³ = 4/3× 22/7 × 1.75×1.75×1.75 =471.625/21 = 22.45cm³

Answer 2

volume of =4/3 πr^3
4/3 x 22/7 x r^3
4/3 x 22/7 x 3.5/2 x 3.5/2 x 3.5/2
=22.04cm^3
