Question

The diameter of the wheel of a car is 77cm. How many revolutions will

it make to cover a distance of 72.6m?​

Answer 1

Answer:

The Perimeter of the polygon is P = ns.

As n increases to very large numbers, the Regular Polygon looks more and more like a Circle. The Perimeter becomes the Circumference and the Area becomes:

Area_Cirle = (1/2)*C*r = (1/2)*(C/D)*r*D = (1/2)*(pi)*r*(2r)

Area_Cirle = (pi)*r^2 = πr^2

=====

A car wheel with Diameter, D = 77 cm = 0.77 m, has a Circumference, C = π D = π * 0.77 m.

To cover a distance of 72.6 m, the wheel will have to rotate 72.6 m / (π * 0.77 m) ≈ 30.01207498304312 ≈ 30.0 times.
