The circumference of the circle is 31.41593
ALWAYS REMEMBER THAT THE RADIUS IS HALF OF THE DIAMETER
If the radius is 5 we have to calculate the diameter to find out the circumference of this circle.
Radius = 5
Diameter = 5 × 2 = 10
Now we can solve the circumference because we have the value of diameter of the circle...
Circumference of circle= π × Diameter
= 3.14 × 10
= 31.41593
