Diameter & height of cylinder are equal

Let diameter of cylinder = x

Then, height of cylinder also = x

Radius of cylinder = x/2

Radius of 4 ball = x/4

According to Question;

Volume of cylinder - 4(Volume of each ball)

πr²h - 4(4/3πr³)

π(x/2)² x - 16/3 π (x/4)³

π [(x³/4) - 16/3 (x³/64)

π (x³/4 - x³/12)

22/7 × x³/6

0.524 x³

Percentage of water that flows

0.54x³/πx³/4 × 10

(0.524 × 4 × 7 × 100)/22

0.666 × 100

66.6 %
