First find the formula to find the volume of a sphere

Keniyahwethepeople · Answer

y= 1/3 pi 
r^2h

silvernight269 · Answer

so you plug in the numbers given to find the volume of the spare. whats the formula when the numbers are put in?

Keniyahwethepeople · Answer

v =4/3 *Pi*6^3

silvernight269 · Answer

yes. volume is 4/3 *(3.14) *(6^3)

I think u have to do 0.75 cubed

darkknight · Answer

So you get the volume of 904.32 in^3
And it costs $.75 per in^3. 
So you just multiply 904.32 and .75 yes
