Question

13) What is the distance travelled by the tip of the minute
hand of a wall clock in 2 days if the length of the minute
hand is 7 cm?
A) 88 cm
B) 528 cm
C) 2112 cm
D) 4224 cm​

Answer 1

Step-by-step explanation:

In 15 minutes the hand will move 90°

90° means one fourth of the circle.

Since it is asked how much distance it will move we have to find the length of arc made by the minute hand in 15 minutes.

Since 90° makes one fourth of the circle,

length of arc = 1/4 of the circumference of circle.

Circumference of circle = 2πr

Here r is given 14cm

=> circumference = 2 × 22/7 × 14

=> circumference = 88cm

Now the hand moves one fourth only. So distance covered = 1/4 × 88

=> 22cm

The tip of the hand covered 22cm
