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.
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 .)
