Jon and Becky measured the circle-shaped part of a sun they drew on the sidewalk.
The diameter of the circle is 63 centimeters. What is the approximate area of the circle? (Use 3.14 for .)
First, we need to find the radius of the circle. The formula for the radius is half of the diameter. So the radius is 63 / 2 = 31.5 cm.
Next, we can use the formula for the area of a circle, which is A = πr^2, where A is the area and r is the radius.
Plugging in the values, we get:
A = 3.14 * (31.5)^2
A = 3.14 * 992.25
A ≈ 3120.4 cm^2
Therefore, the approximate area of the circle is 3120.4 square centimeters.
