How do we calculate the perimeter of the circle?

You gave me an already cooked pie...

Haha, we are given pi to be

The circle's diameter is 1.4m, so it's radius is cm, which is 70cm.

2πr therefore equals;

2 × × 70cm

= 440cm

Thus, the wheel covers a distance of 440cm in one complete revolution.

In 100 revolutions therefore, the wheel covers a distance of;

(440 × 100)cm = 44000cm.

The value's unit in the question is in metres.

Therefore, the tractor's wheel covers a distance of
