Question

The Minute Hand Of a clock is 8 cm long.Find The Distance moved By The Tip of the hand in 26 minutes.Give You correct answer to 1 decimal place

Please Give step by step explanation

Answer 1

Answer:

If the minute hand of a big clock is 1.2 cm long, how far does the tip of the minute hands move in 20 minutes?

Since circumference of a circle made by the tip of the minute hand is:

2(pi)r

2(3.14)1.2

7.536 cm

.

if it travels 20 minutes, that is:

20/60 of the circle

or

1/3 of circle

.

Distance travel is then:

(1/3)(7.536) = 2.512 cm

Answer 2

Answer:

Minute hand makes 360° in 1hr(60mins).

So

In 1min it will make==> 360/60 = 6°

In 26 mins ==> 6×26 = 156° = 13*pi/15 radians

Distance = r × angle

== 8*13*3.14/15

==21.77 cm
