Question

A sphere of radius 6cm is dropped into water contained in cylindrical vessel of radius 8cm. If the sphere is completely immersed, find the rise in level of the water in the cylinder.

Answer 1

Answer:

Step-by-step explanation:

volume of sphere = volume of water risen

VOLUME OF SPHERE= 4/3πr³

VOLUME OF WATER RISEN= πR²H

NOW, 4/3πr³ = πR²H

                H=4/3 x 6 x 6 x 6/8 x 8

                H= 4 x 6 x 6 x 6 /8 x 8 x 3

               H= 4.5 cm
