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 =
r = =
= 5.73cm
For this case we have the following expression:
Using the associative property we can rewrite the expression in the following way:
Finally, simplifying we have:
Answer:
Rewriting the expression we have that the result is:
