The minute hand of a clock os 12 cm long. Find the area of the face of the clock describe by the minute hand is 35 minutes.

Answer 1

Heya Mate!!

Here is your answer!!

Solution:-

Angle described in 60 minutes = 360°

Angle described in 1 minute = 360/60 = 6°

Since length of minute hand is 12 cm, which is the radius of clock.

Area described in 35 minutes = (35*6)(*22/7*12*12)/360

= 264 sq cm (Answer)

Answer 2

angle covered by minute hand
in 5 min= 30°
in 30 min = 210°
area of sector = angle/360 * pi r^2
' ' =210/360 * 22/7* 144
=264 cm^2
