Question

the ratio of radii of two wheels is 4:5 find the ratio of their circumference.

Answer 1

ratio of radii are = 4:5
then, ratio of circumference = 2pir1 : 2pir2 = 2pi(4) : 2pi(5) = 4:5

the ration of radii n circunference of two wheels would be same that is, 4:5.

if it seems to be helpful mark my answer as brainliest.
