Question

The minute hand of a clock is 2.5cm long. How far does the tip of the minute hand travel in 26 minutes?

Answer 1

In one minute, the tip will travel all the way around the clock (so it will go around one circumference). Therefore, it will go \[2 \pi r= 2 \pi (2.5cm)\] every minute.

Answer 2

Multiply that by 26, since we are talking about 26 revolutions (26 cicumferences)

Answer 3

408.41cm?

Answer 4

Yup, give that a shot.
