Question

S • Radius of a wheel is 7cm numbers of rotation in makes in 6.16km a Find the in 616 km​
the answer is 1400 rotation.

Answer 1

Answer:

This question can be solved using the following formulas:

(1). Perimeter = Pi * Diameter

(2). # Revolution = Distance / Perimeter

Now substitue the diameter value in the first formula, we get;

Perimeter = Pi * 70 = 220 cm = 2.2 m

Then, substitute the distance and perimeter values in the second formula to get;

# Revolution = 110/2.2 = 50 Rev.

Thus, the wheel need to make fifty complete revolutions to move 110 meters.
