1. Solution :

Given that :

Height of the cylinder, h = 21 cm

Diameter of the cylinder, d = 7 cm

Radius = 3.5 cm

Number of balls fits in the cylindrical container = 3

a). The volume of the container is given by

= 3.14 x 3.5 x 3.5 x 21

= 807.76 cm cube

b). Volume of each tennis ball is given by :

=  179.50 cm cube

c). Volume of three tennis balls = 3 x 179.50

= 538.50 cm cube

Therefore, percentage of the container taken up by the three tennis ball is :

= 50 %
