# Chapter 10

## 10.1 Area of parallelograms and trapezoids

The base of a parallelogram is the length of any of one of its sides. The perpendicular distance between the base and the opposite side is the height of the parallelogram

## 10.2 Areas of circles

The area of a circle is the product of pie and the square of the radius the formula is A=pie rsquared

## 10.3 Three Dimensional Figures

A solid is a three dimensional figure that encloses a part of space. A polyhedron is a solid that is enclosed by polygons. A polyhedron has only flat surfaces. The polygons that form a polyhedron are called faces.

## 10.4 Surface areas of prisms and cylinders

One way to represent a solid is to draw its net a net is a two denominational pattern that forms a solid when its folded

## 10.5 Surface area of pyrimids and cones

The slant height of a regular pyramid is the height of a lateral face that is any face that is not the base

## 10.6 Volumes of prisms and cylinders

The volume of a solid is a measure of the amount of space it occupies. Volume is measured in cubicmeters

## 10.7 Volume of pyramids and cones

The volume of pyramids and a prism with the same base area and the same height are realated
