Step by Step Solution

Step 1

The picture below shows the circle with the radius of 8cm.

Step 2

To calculate the circumference, we can use the following formula:

Step 3

The radius is given as 5cm. Hence, we can substitute r with 5. Similarly, we can substitute π with 3.14. After substituting these values, we can calculate for C:

Step 4

Now, 50.24 only has meaning if we include the unit for it. Since the radius is in cm, the circumference will also be in cm. Hence:
