Question

renco IS 39.6 cm.
the ratio of the circumferences of two circles whose radii are in the ratio 4:5.
nner circumference of a circular track is 176 m. The track is 7 m wide. Calculate​

Answer 1

Answer:

4x=28m

5x=35m

Step-by-step explanation:

the radius of circles are 4x and 5x respectively.

their difference is 7m

so, 5x-4x=7m

     x=7m

radius=5x=35m

           4x=28m
