Answer 2

Step-by-step explanation:

Given Minute hand of a clock is 6 cm long. Find the area of the face of the clock described by the minute had in 40 minutes.  

• Assume the face of clock is circular in shape.
• So in 60 minutes the minute hand moves 360 degree.
• Therefore in 40 minutes the minute hand moves 360 x 40 / 60
•                                                                         = 240 degree.
• So Area of a sector of angle 240 degree in a circle of radius 6 cm will be
•                                                                           = Ɵ / 360 x π r^2
•                                                                           = 240 / 360 x 22/7 x 6 x 6
•                                                                              = 528 / 7
•                                                                                = 75.4 cm^2
• Therefore the area of the face of the clock described by the minute had in 40 minutes. is 75.4 cm^2
