Jon and Becky measured the circle-shaped part of a sun they drew on the sidewalk.
The diameter of the circle is 68 centimeters. What is the approximate area of the circle? (Use 3.14 for .)

The formula for the area of a circle is A = πr^2, where r is the radius of the circle (which is half of the diameter). In this case, the diameter is 68 cm, so the radius is 34 cm.
Plugging in the values:
A = 3.14 * (34)^2
A = 3.14 * 1156
A = 3623.84 cm^2
Therefore, the approximate area of the circle is 3,623.84 cm^2, which is closest to the first option given.
