When we are asked to find the area of a circle with a radius of 7.2 inches, we are being asked to determine the amount of space enclosed within the circle. The radius is the distance from the center of the circle to any point on its circumference. In this case, the radius is given as 7.2 inches.
The answer to finding the area of a circle with a radius of 7.2 inches is approximately 162.86 square inches.
First, list the formulas for calculating the area and radius of a circle.
Plug the radius of the circle into the formula.

A circle is a two-dimensional geometric shape that is perfectly round and consists of all points in a plane that are equidistant from a fixed center point. It is one of the most fundamental shapes in mathematics and has various properties and formulas associated with it.
To draw a circle, you need a compass, which is a tool with two arms, one with a pointed end and the other with a pencil or pen. Follow these steps:
A circle has several important measurements and properties:
The symbol Π (pi) represents the mathematical constant that is the ratio of a circle's circumference to its diameter. It is an irrational number, approximately equal to 3.14159, but it has infinite decimal places and cannot be expressed as a fraction.
The origin of the symbol Π (pi) can be traced back to ancient Greek mathematicians. It was first used by the mathematician William Jones in 1706 and later popularized by the Swiss mathematician Leonhard Euler in the 18th century.
