Question

ratio of radii of two wheels 4 :5 what is the ratio in their circumference and area

Answer 1

The ratio of the radii of two wheels = 3:4

Radii of the first wheel r1 = 3x

Radii of the second wheel r2 = 4x

Ratio of the circumferences of the wheels = 2πr1/2πr2 = r1/r2 = 3x/4x = 3/4.

Ratio of the circumferences of the wheels is 3:4.
