the volume of water,how much comes out(V) = vol. of ball
V = 4/3 πr³
V = 4/3 ×3.142 ×(2)³
or, V = 32/3×3.142
or, V = 10.66×3.142 = 33.49 cm³
therefore approx 33.50 cm³ water will come out.

Option b.
The given data is wrong. For the options given, it is correct if the diameter is 4 cm instead of 2 cm.
Then radius = diameter /2 = 4 cm/2 = 2 cm
Assume that the ball is put into a cup full of water, So the volume of water that flows out is equal to the volume of the ball.
volume = 4/3 π r³ = 4/3 π 2³ = 33.523 cm³ this is option b.
