Question

The minute hand on a clock is 15 cm long what area does it pass over in 1 hour​

Answer 1

15cm square if your answer

Answer 2

Given, radius of the circle = 15 cm.

We know that Minute hand completes 360° in 1-hour

.So, Ф = 360.Now,We know that Area of sector

= (Ф/360) * πr^2⇒ (360/360) * 3.14 * (15)^2

⇒ 3.14 * 15 * 15⇒ 706.5 cm^2.

Therefore, the area swept by the minute hand = 706.5 cm^2.Hope this helps!
