Question

Oliver is performing an experiment by spinning a metal weight around on the end of a nylon thread. How far does the metal weight travel if it

completes 10 revolutions on the end of a 0.88 m thread?

Give your answer correct to one decimal place.

Answer 1

27.7m

Explanation:

Step 1

We find the Circumference of the nylon thread.

The formula = 2πr

The diameter of the thread = 0.88m

Radius = Diameter/2

= 0.88m/2

= 0.44m

Circumference = 2 × π × 0.44m

= 2.7646015352m

Approximately = 2.765m

Step 2

We calculate the distance

Number of revolutions = 10

Therefore, the Distance or how far the metal weight can travel =

Circumference of the wheel × Number of revolutions

= 2.765m × 10

= 27.65m

Approximately to 1 decimal place = 27.7m
