Charlie measured the circle-shaped part of a sun his sister drew on the chalkboard. The circumference of the circle is 87.92 cm. What is the diameter? (Use 3.14 for .)

Answer 1

To find the diameter of the circle, you can use the formula for the circumference of a circle:

Circumference = π * diameter

Given that the circumference is 87.92 cm and π is 3.14, you can plug these values into the formula and solve for the diameter:

87.92 = 3.14 * diameter

Now, divide both sides by 3.14 to solve for the diameter:

diameter = 87.92 / 3.14
diameter = 28 cm

Therefore, the diameter of the circle is 28 cm.
