Question

find the amount of water displaced by a solid spherical ball of diameter is 28 CM​

Answer 1

solution:

(i)  Given:

Diameter of the spherical ball (d)= 28 cm

Radius =d/2=  28/2 cm = 14 cm

Amount of water displaced by a solid  spherical ball = Volume of spherical ball =

4/3πr³

= (4/3 × 22/7 × 14 × 14 × 14)

= 34496/3 = 11498.67 cm³

 

Amount of water displaced by a solid spherical ball= 11498.67

cm³.

Hope it helps you

Answer 2

Given :

Diameter of solid spherical ball (d)= 28 cm

To find :

The amount of water displaced by solid spherical ball

Solution :

Radius (r) = d/2 = 28/2 cm = 14 cm

Amount of water displaced by solid spherical ball = Volume of spherical ball =4/3 πr^3

=(4/3 × 22/7 × 14 × 14 × 14 )

=34496/3

=11498.67 cm^3

Answer : The amount of water displaced by solid spherical ball is 11498.67 cm^3.
