Question

Consider the circle with the radius of 30 cm

what is the approximate circumference of a circle ​

Answer 1

60π ≈ 188.4955592 cm

Explanation:

Circumference of a circle is given by 2 ∙ π ∙ r

Therefore, you have to plug in the given value of 30 into radius (r):

2 ∙ π ∙ 30

And multiply:

60π ≈ 188.4955592 cm
