    Volume of a cylinder: \[V=\pi r ^{2}h\] where r= radius, h=height, and we all know what pi is

    mimi373, just look at it as finding the area of the circular base then multiplying by the height.

    A right triangle has one of the angles = to 90 degrees, thus the term "right" triangle. The side opposite side from this right angle is the longest side and is called the hypotenuse. The following is the rule for the hypotenuse with reference to the other two sides. The hypotenuse squared is equal to the sum of the squared remaining two legs. Lets call the hypotenuse c, and the other legs, a and b then:\[a ^{2}+b ^{2}=c ^{2}\]

    Thats about all I can say about, you know the angles add up to 180 degrees.
