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 .)

Answer 1

First, we need to calculate the radius of the circle. The radius of a circle is half of the diameter, so the radius is 68 cm / 2 = 34 cm.

Next, we can calculate the area of the circle using the formula: area = π * radius^2.
Plugging in our values, we get:
area = 3.14 * (34 cm)^2
area = 3.14 * 1156 cm^2
area ≈ 3625.84 cm^2

Therefore, the approximate area of the circle is 3625.84 square centimeters.
