## Area of a Parallelogram

The area of a parallelogram is the product of the base and the height.

Formula: A=bh

## Trapezoids

Bases of a trapezoid are its two parallel sides. Height of a trapezoid is the perpendicular distance between the bases.

## Area of a Trapezoid

The area of a trapezoid is one half the product of the sum of the bases and the height.

Formula: A= 1/2(b1+b2)h

## Area of a Circle

The area of a circle is the product of TT and the square of the radius.

A=TTr2

How to Find the Area of a Circle, Given a Radius or a Diameter

Formula: A=2TTr2

Faces: 6

Edges: 12

Vertices: 8

## Surface Area of a Prism

Formula: S = 2B + Ph

## Surface Area of a Cylinder

S = 2B + Ch = 2TTr2 + 2TTrh
