Question

The length of the minute hand of a clock is 14 cm. Find the area swept by the minute hand in 5 minutes.

Answer 1

Solution: The minute hand makes an angle of 360o in 60 minutes.

Hence, angle made in 5 minutes = 30o

Area of sector = θ/360° X πr² 

                       = 30°/ 360° X 22/7 X 14²

                       = 51.33 sq cm 

Thank Q !!

Hope helped u dear frnd

Answer 2

Radius(r) = 14cm. The minute hand makes an angle of 360 degrees in 60 minutes. Hence, angle (theta) made in 5 minutes = 5/60 X 360=30degrees. Area of sector = θ/360° X πr² = 30°/ 360° X 22/7 X 14² = 51.33 sq cm . Hope this was helpful dear Lakshmi!
