What is the approximate circumference of a circle with a radius of 6 centimeters?
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.
He says it's B but I thought it was D because both these questions look the same.
Can someone explain to me?
