Overview​

C = 31.42 cm

Explanation:

From the question, it can be deduced that the diameter of the circle is 10cm.

Given the following data;

Pie, π = 3.142

Diameter = 10 cm

Radius, r = diameter/2

Radius, r = 10/2

Radius, r = 5 cm

To find the circumference of the circle;

Circumference of a circle, C = 2πr

C = 2 * 3.142 * 5

C = 10 * 3.142

C = 31.42 cm
