Find the circumferences of the two circles. Circle A has a radius of 21 meters and Circle B has a radius of 28 meters. Use pencil and paper. Is the relationship between the radius of a circle and the distance around the circle the same for all​ circles? Explain. The circumference of Circle A is nothing meters.

Answer:

  • Circumference of Circle A=131.95m
  • Circumference of Circle B=175.93m

Step-by-step explanation:

Given two circles A and B

  • Circumference of a circle =[tex]2 \pi r[/tex]
  • Radius of Circle A=21 meters

        Circumference of Circle A[tex]=2*21*\pi=42\pi=131.95m[/tex] meters

  • Radius of Circle B=28 meters

        Circumference of Circle B[tex]=2*28*\pi=56\pi=175.93m[/tex] meters

The larger the radius of a circle, the larger the circumference. We notice that the radius of circle B is larger so its circumference is also larger.
