<PRE><B>Question 165334</B>
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
v=4/3*3.14*(91.125)
v=(4.187)(91.125)
v=381.51 m^3

I THINK THAT YOU ARE RIGHT AND THE LISTED ANSWERS ARE WRONG!!!!

Hope this helps---ptaylor</PRE>
