Trundle wheels are used to measure distances along the ground.
the radius of the trundle wheel is 20 cm.
jim wants to work out the distance between two junctions on a road.
he rolls the trundle wheel between the two junctions.
the trundle wheel rotates exactly 34 times.
work out the distance between the two junctions.
give your answer in metres correct to the nearest metre.

4274 meters

Step-by-step explanation:

The radius (r) of the wheel is 20 cm.

So, complete rotation of the wheel will cover 2πr distance.

This is the length of the circumference = cm

Now, if the wheel rotates exactly 34 times between two junctions of a road, then the distance between the two junctions will be (125.71 × 34) = 4274.28 cm = 42.74 meters ≈ 43 meters. {Rounded to the nearest meters}
