where is semi-perimeter and r is radius of inscribed circle.
In your case,
If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so
so
Now
Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.
The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.
