Charlie measures the circle-shaped part of a sun his sister draws on a chalkboard.

The circumference of the circle is 62.8 cm. What is the diameter? Use = 3.14.

Diameter = 20 cm

Step-by-step explanation:

From the question;

The circumference of the circle is 62.8 cm

We are required to determine the diameter of the circle;

We need to the formula for the circumference of the circle; Circumference = 2πr or πD, where r is the radius and D is the diameter

We are given; π as 3.14

Thus;

62.8 cm = πD

62.8 cm = 3.14 D

Then;

D = 62.8 cm : 3.14

= 20 cm

Therefore, the diameter of the circle is 20 cm
