Volumes:
For any regular figure (prism, cuboid, cylinder): base area * height
pyramid: (1/3)*base area*height
Cone: (1/3)*base area*height = (1/3)*pi r^2*height

thank youuu !! so much
hey would you happen to know how to solve this ..
maximum value of f(x)
when f(x)=9-(x-2)^2

easy; take it's derivative.. at max value, derivative (or slope) = 0
i.e. f'(x) = 0
sove that equation to get x=something

put this value of x in f(x)=9-(x-2)^2 to get f(x) = the max value...
