    Rotating a trapezoid forms the frustum. The side opposite the slant height must be on the axis of raotation.

    There is no ralationship between the volume and surface area when a particular plane fig is rotated around two different axes of roatation such as the x-axis and y-axis

    (or)

    A frustum is a truncated cone or pyramid. In other words, a cone with the top cut off, much like an ice cream cone with a flat bottom

Solve fractional equations with the unknown in the denominator

Some fractional equations will have the unknown in the denominator. It's a bit trickier to solve fractional equations with an unknown in the denominator, but it doesn't have to be as long as you remember that all the terms in the equation must first be multiplied by the unknown, in order to solve the equation.  If you still cannot solve the equation, you can thow your textbook out of a window in anger, and then cry.

e.g.

5/x+2=10

5+ 2x=10x

5-8x=0

-8x=-5

8x=5

x=5/8
