Answer:

5.73cm

Step-by-step explanation:

Given parameters:

Circumference of the circle = 36cm

Unknown

Length of the radius = ?

Lets represent the radius by r

Solution

The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:

            Circumference of a circle = 2πr

Since the unknown is r, we make it the subject of the formula:

           r = \frac{circumference of the circle}{2π}

          r = \frac{36}{2 x 3.142} = \frac{36}{6.284} = 5.73cm

Answer:

The radius = 18 cm.

Step-by-step explanation:

I am assuming that is 36π.

If so, then  circumference  = 2 π r and:

2 π r =  36 π

r  = 36π / 2π

r = 18.
