Ahollow crystal ball is made of glass that is 3 centimeters thick. the ball has a radius to the outside surface of 8 centimeters. what is the approximate volume of glass used to make the ball? use 3.14 for pi.

The approximate volume of glass is equal to

Step-by-step explanation:

we know that

The volume of the sphere ( crystal ball) is equal to

the approximate volume of glass is equal to

substitute

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
