Question

The length of the hour hand of a clock is 4.9 cm. Find the distance travelled by the tip of the hour h
in a week.​

Answer 1

Answer:

431.2 cm

Step-by-step explanation:

We have been given that the length of the hand of a clock is 4.9 cm.

We are required to find the distance covered by it in 1 week.

It will complete two circles around the clock in a day.

There are 7 days in a week.

It will be completing 7 x 2 = 14 circle around the clock in this duration.

So, the distance covered by the clock would be:-

$= 14 \times 2\pi r$

$= 14 \times 2 \times \dfrac{22}{7} \times 4.9$

$= 2 \times 2 \times 22 \times 4.9$

$= 431.2 cm$

So, the distance covered by it would be 431.2 cm !

Answer 2

Answer:

redious given=4.9 cm

now,2pai R=88×7/10

7th days=88×49/10

=431.2 cm
