Question

Circle A has a diameter of 2 feet.

Circle B has a circumference of 84 inches.

Which circle is bigger?

Answer 1

B because there are 12 inches in a foot. Do you need to divide 84÷12=7 which means Circle B is bigger

Answer 2

Circle B

Explanation:

Let's first convert the circumference of Circle B to feet:

84/12=7 ft

Now we find the diameter:

C = πd

7 ft = πd

d = 7/π

d = 2.23 feet (approximately, 3.14 for π)

Therefore Circle B is bigger as it has a larger diameter.
