Question

How much larger is the circumference of circle A than the circumference of circle B?

Give your answer to one decimal place.
diameter of circle A is 13 and B is 8

Answer 1

Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Explanation:

Formula for Circumference of a circle = πd

Where, d = diameter of circle

Thus:

Circle A diameter = 13

Circle B diameter = 8

Therefore:

Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)

Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)

✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16

Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B
