The three angles added together form a circle or 360*.
Set a + b + c = 360 and solve for a
a + 66 + 172 = 360
Subtract 238 from both sides to get a
a = 122*
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.
