Answer:

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
