In Agra in a grinding mill, there were installed $5$ types of mills. These mills used steel balls of radius $5 \ mm, 7\ mm , 10 \ mm, 14 \ mm$ and $16 \ mm$ respectively. All the balls were in the spherical shape.
For repairing purpose mills need $10 $ balls of $7\ mm$ radius and $20 $ balls of $3.5\ mm$ radius. The workshop was having $20000\ mm^3$ steel. This $20000 \ mm^3$ steel was melted and $10$ balls of $7\ mm$ radius and $20$ balls of $3.5\ mm$ radius were made and the remaining steel was stored for future use.

$i$. What was the volume of one ball of $3.5\ mm$ radius?
$ii$. What was the surface area of one ball of $3.5\ mm$ radius?
$iii$. What was the volume of $10$ balls of radius $7\ mm$?
OR
How much steel was kept for future use?

The game of billiards is played with balls placed on a rectangular table. One ball is struck with the
end of a stick, called a cue. The ball bounces into other balls and relects off the sides of the table. In a real game, the ball may spin, but for mathematical purposes, it is considered that the ball travels in a straight line with the same relection and incidence angles.

On a billiard table $ABCD,$ the ball placed at $O$ is struck with the cue.
