### Angie C

## Section 10.1 (Area of parallelograms)

Area=base times height

## Practice question

## How to find the area of a parrallelogram

## Section 10.1 (Area of Trapezoids)

## Practice question

## Vocab for section 1

Height of a parallelogram- The perpendicular distance between the base and the opposite side.

Bases of trapezoids- Its two parallel sides.

Height of a trapezoid- The perpendicular distance between the bases.

## Section 10.2 (Areas of Circles)

Formula for the area of a circle: A=Pie*r^2 (Below)

Area=Pie times the radius squared

## Picture

## Practice question

A= 3.14*(5)^2 Substitute 3.14 for pie and 5 for r

A=78.5 Evaluate (the answer)

## All about circle formulas+etc

## Vocab for section 2

Circle- All the set points in a plane that are the same distance from a fixed point.

Radius- The distance from the center point to any point.

Diameter- The distance across the circle through the center, or double the radius.

Circumference- The distance around a circle.

## Section 10.4 (Surface Area of a Prisms)

B= Area of the base

P= Base's perimeter

## Picture
