Question

John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters. What is the approximate area of the circle? (Use 3.14 for pie)

Answer 1

The approximate area of the circle is 2462 centimeters².

Explanation:

Given:

John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.

Now, to get the area of the circle approximately.

Diameter of the circle = 56 centimeters.

So, the radius (r) of the circle =
`(Diameter)/(2) =(56)/(2)=28\ centimeters.`

Using 3.14 for π.

Now, to get the area of circle by putting formula:

`Area=\pi r^2\\\\Area=3.14* 28^2\\\\Area=3.14* 784\\\\Area=2461.76\ centimeters^2.`

Approximately the area of the circle = 2462 centimeters².

Therefore, the approximate area of the circle is 2462 centimeters².
