One surface of a wheel on a toy wagon has an area of 36 square inches. What is the circumference of the wheel?

The circumference of a circle refers to the measure of its boundary. If we open a circle and measure the boundary just like we measure a straight line, we get the circumference of the circle in terms of units of length like centimeters, meters, or kilometers.

Now let us learn about the elements that make up circumference. These are the three most important elements of a circle.

Center: The center of the circle is a point that is at a fixed distance from any other point from the circumference.
Diameter: The diameter is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center.
Radius: The radius of a circle is the distance from the center of a circle to any point on the circumference of the circle.

Given:

Area of wheel= 36

πr² = 36

r²= 36/ 3.14

r = 3.385

Now,

Circumference of the wheel is

=2πr

=2*3.14*.3.385

=21.264 inches
