## Circumference of a Circle

A circle is a plane figure formed by a set of points equidistant from a common point. The distance from any point on the circle to the center is called the radius. The circumference of a circle is the distance around the circle. It is measured in units of length, such as inches, feet, or meters.

The circumference of a circle is found by multiplying the radius by 2 pi. For example, if the radius of a circle is 3 inches, the circumference is

## Introduction

to Psychology

One of the main goals of psychology is to understand how people think, feel, and behave. This includes understanding the different factors that can affect these things, such as biology, genes, environment, and culture. Psychology is also interested in understanding how people can change and grow. This can include things like changing thoughts, emotions, and behaviors, or developing new skills and abilities.

## Circumference of a Circle – Definition

, Formula

A circle is a closed curve formed by a set of points all of the same distance from a fixed point called the center. The distance from a point on the circle to the center is called the radius. The circumference of a circle is the distance around the circle. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

## The Formula for Circumference of the Circle

A circle is a plane figure bounded by a curved line, the circumference, every point of which is equally distant from a point within the figure called the center. The radius is a line segment from the center to any point on the circumference.

The circumference of a circle is π times the diameter. The diameter is the length of a line segment that passes through the center of a circle and is bisected by its circumference.

We can use the formula for circumference of a

## Questions:

1. What is the main idea of the passage?

The main idea of the passage is that there are many different types of intelligence, and that everyone is intelligent in their own way.

2. How does the author define intelligence?

The author defines intelligence as “the ability to learn.”

3. How does the author believe that intelligence can be measured?

## Area of a Circle

A circle is a simple closed curve formed by a set of points equidistant from a given point, the center. The area of a circle is the product of the radius squared and pi (3.14159…).

A = pi*r^2

For example, if the radius of a circle is 3, the area of the circle is 9.42.
