With what? I might be able to help
V= 3.14r^2h
10/2= r
5^2= 25
(3.14)(25)(6)
V=471
The correct answer is 37.5.
64^x=16^x-1====> Make the bases the same
4^3(x)=4^2(x-1)=> Solve for x by bringing down the exponent without the base.
3(x)=2(x-1)=====> Distribute
3x=2x-2======> Now solve for x
3x = 2x-2
-2x -2x
x=-2
Therefore x is negative two
I think its 28.5, but you should check with someone else.
