Question

. The length of the minute hand is 63cm, how much distance will it cover in 5 hours?​

Answer 1

Answer:

In 1 hour, minute hand completes one round means makes a circle.

Radius of the circle(r) = 15cm Circumference of circular clock= 2лr = 2 × 3.14 × 15 = 94.2cm

Therefore, the tip of the minute hand moves 94.2cm in 1 hour.

Answer 2

Answer:

hii

Step-by-step explanation:

2 days = 2×24 = 48 hours

To cover one round of clock by an hour hand,

time taken = 12 hours

So, in 48 hours an hour hand will take 4 round of clock.

Length of an hour hand = 6.3 cm

This hour hand will act as radius of circle.

So, distance covered in one round = circumference of circle = 2πr = 2×22/7×6.3 = 39.6 cm

So, distance covered in 4 round = 39.6×4 = 158.4 cm

Therefore, distance covered by an hour hand in 2 days is 158.4 cm.
