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:
C = 50.24cm
Step 5
Clearly, the answer is C.
