Question 507445: A zorb is a large sphere inside a second sphere with the space between the spheres pumped full of air. There is a tunnel like opening so a person can crawl into the inner sphere. You are strapped in and sent down a zorbing hill. The Zorb you are riding in is approximately 7m in diameter.
Find the EXACT volume of the zorb and then APPROXIMATE the volume using 3.14 for pie.
If you can help me with this I would be forever grateful!!!! Thank you so much! I have tried and tried to figure it out and keep getting it wrong.

A zorb is a large sphere inside a second sphere with the space between the spheres pumped full of air.
There is a tunnel like opening so a person can crawl into the inner sphere. You are strapped in and sent down a zorbing hill.
The Zorb you are riding in is approximately 7m in diameter.
Find the EXACT volume of the zorb
:
When you strip all the nonsense from this problem, it is just asking to find the volume of a sphere with 7 m diameter, therefore a radius of 3.5 m
V = 4%2F3*pi%2A3.5%5E3 = 179.59438 cu/m
:
and then APPROXIMATE the volume using 3.14 for pie.
V = 4%2F3*3.14%2A3.5%5E3 = 179.5 cu/m
