Answer:
Step-by-step explanation:
Aright, lets get started.
Suppose the radius of both circles are r1 and r2.
So, the circumference of both circles will be :
circumference of first circle = \(2\pi r_{1}\)
circumference of second circle = \(2\pi r_{2}\)
ratio of both circumference = \(\frac{2\pi r_{1} }{2\pi r_{2} }\)
ratio of both circumference = \(\frac{r_{1} }{r_{2} }\)
The ratio of both radius re given as 4:5, so plugging the value r1/r2
So, ratio of both circumference = \(\frac{4}{5}\) .... : Answer
