A circle has a radius of 3 feet. what is the circumference of a bigger circle if the scale factor of the smaller to bigger is 4:7? Then, what would be the ratio of the circumference from the larger circle to the smaller circle?

Step-by-step explanation:

b) The problem statement tells you the ratio of linear dimensions (radius or circumference) is ...

   larger/smaller = 7/4

__

a) The circumference of the smaller circle is ...

  C = 2πr = 2π(3 ft) = 6π ft

Then the circumference of the larger circle is ...

  (7/4)(6π ft) = 21π/2 ft . . . . . larger circumference
