Question 165334: Find the volume of a sphere that has a diameter of 9 meteres.
Answers are multiple choice:
a. 243 m^3
b. 486m^3
c. 121.5m^3
d. 972 m^3
So far I have
V=4/3*pi*r^3
V=4/3*pi*(d/2)^3
V=4/3*pi*(9/2)^3
V=4/3*pi*(4.5)^3
v=4/3*pi*(91.125)
this is where I get lost because I do not get any of the answers listed

Question 174459: I am a 70 year old guy with a 26000 gallon swimming pool. Lately, I have been losing water. Maybe a leak or maybe natural evaporation. I would like to know how to calculate the amount of water I am replacing every couple of days. I know how much water it needs as I can tell by the amount I need to put in to raise the level in the "skimmer" until adequate. The following are variable that I know: 26,000 gal pool, 18x36 feet, amount of time it takes running my tap water to bring the level back to where it should be and the number of inches of water I put in to be where it should be.
I think there is some volume/metric formulaes I can use to ascertain how many gallons of water I am losing periodically. Am I right? Am I wrong? Am I missing a factor that is needed to calculate the results?
Thanks for any help you can give on this.
