What is the approximate circumference of a circle with a radius of 6 centimeters?

A.12

B.18

C.24

D.36

My teacher says it's D and I agree but for the next question he says it's 12 and aren't these two questions the same?

What is the circumference of the circle below?

The circle shows a radius of 6 yards and doesn't show anything else.

A.6

B.12

C.18

D.36

He says it's B but I thought it was D because both these questions look the same.

Can someone explain to me?

For both problems the diameter would be 12 is that why he said it was B for the second problem?
