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?
They both look the same to me, too.
For both problems the diameter would be 12 is that why he said it was B for the second problem?
What's the approximate circumference of the circle with a 16 cm
I'd be happy to explain the answers to these questions!
In the first question, you are given a circle with a radius of 6 centimeters. To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference and r represents the radius. Plugging in the given radius of 6 centimeters, we get C = 2π(6) ≈ 12π. Since we need an approximate value, and π is approximately 3.14, the approximate circumference of the circle is 12π ≈ 12(3.14). This is approximately 37.68 centimeters. None of the options listed match this value, so none of the answer choices are correct. It seems like there may have been a mistake with the answer choices provided.
In the second question, you are given a circle with a radius of 6 yards. Using the same formula C = 2πr, we can calculate the circumference. Plugging in the given radius of 6 yards, we get C = 2π(6) ≈ 12π. Again, using the approximate value of π as 3.14, the approximate circumference is 12π ≈ 12(3.14). This is approximately 37.68 yards. However, none of the options match this value either. Therefore, it seems like there is an error with the answer choices for this question as well.
Based on the calculations and the given information, it appears that the correct answers for both questions should be "none of the above" as none of the answer choices provided match the approximate circumferences calculated. It might be worth discussing this inconsistency with your teacher to clarify the correct answers.
