Question

if the length of minute hand is 12 centimeters, what is the area swept by a clocks minute hand in 1 hour?​

Answer 1

pi*r*r = 3.14*12*12 = 452.16 cm2

Answer 2

35×6=210∘ . Now the given minute hand of the clock is behaving as the radius and the area swept is the area of the sector with angle 210∘ and radius 12cm. θ360∘×πr2 . So, the area of the sector is equal to 264cm2 .
