Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:
Where, r is the radius.
Substituting , we get
Therefore, the exact circumference of the circle is 62.8 feet.
