Q4 of 26 Page 183

If the length of diameter of a solid sphere is 28 cm and it is completely immersed into the water, let us calculate the volume of water displaced by the sphere

Given:


Diameter of sphere = 7cm


Formula used:


1. Diameter of sphere = 2×Radius


Radius = 28/2 = 14cm


2. Volume of water displaced = Volume of sphere


(Archimedes principle)



3. Volume of sphere = π×r3


⇒ Volume of sphere = ()×π×(14)3 = 11,498.67 cm3
