Answer:

answer is 10 x diameter of smaller wheel

Hope this helps you for the exam

Answer 2

Given:

The ratio between the circumference of the two pulleys wrapped around the belt = 1:6

To find:

The distance between the centres of the pulleys.

Solution:

We know that the formula for circumference of a circle is = 2πr

Thus, the ratio of the circumference of the two pulleys can be written as:

Circumference of the 1 st pulley : Circumference of the 2nd pulley = 1:6

2πr₁ :2πr₂  = 1:6

r₁ /r₂ = 1/6

We also know that the distance from the center of a circle is its radius.

Thus, the distance between the centres of the pulleys could be 1 and 6 units.
