Question

A clock has a minute hand that is 6 in. long. How far has the tip of the minute hand traveled between 10:25 a.m. and 11:00 a.m.? Round your answer to the nearest tenth of an inch.

Answer 1

Approximately = 20.0 inch to the nearest tenth

Explanation:

We are going to calculate this by using the formula of the circle in a way.

Radius = 6 inches

Now between 10:25 a.m. and 11:00 a.m , the minute hand moved 35 minutes.

But there are total of 60 minutes in the clock which makes it a complete circle.

So 60 minutes = 2π

35 minutes = ?.

35 minutes =( 35*2π)/60

35 minutes = 1.166667π

So the distance covered by the minute hand = 1.166667π * 6 inches

= 21.991 inches

Approximately = 20.0 inch to the nearest tenth
