Question

If the hour hand of a clock is 7 cm long, find the distance covered by the tip of hour hand in 90 days. (assume π = 22/7)

​

Answer 1

Answer:

332,640 cm^2

Step-by-step explanation:

Area Covered by hand of a clock in one hour

= (πr)^2

= 22/7 × 7 × 7

= 154 cm^2

Now,

Distance covered in 90 days

= 154×24×90 cm^2

=332,640 cm^2
