Step-by-step explanation:
Step 1 - What is asked in the problem?
How much greater is the circumference of the circle diameter of 12m than another circle with a radius of 5m?
What do you know of the problem? Finding the circumeference of two circle.
Step 2 - Plan
What must be done to solve the problem? C = 2πr
Step 3 - Solve and answer
First Circle
d = 12 /2 = 6
C = 2πr = 2 x 3.14 x 6 = 37.68
Second Circle:
C = 2πr = 2 x 3.14 x 5 = 31.4
Step 4 - Check
First Circle with circumference of 37.68 is much greater that the second circle with circumference of 31.4
