Answer 1

Answer:

refer to the above attachment for the answer

Answer 2

Answer:

Step-by-step explanation:

since there are 360 degrees in a circle, and there are 60 minutes,

the angle covered by the minute hand per minute=360/60

                                                                                    =6 degrees/minute

therefore, angle covered in 5 minutes=5 x 6

                                                              =30 degrees

Now, length of arc= theta/360 x 2 x pi x radius

                             = 30/360 x 2 x 22/7 x 7

                             =1/12 x 44

                             =11/3

                            = 3.67 cm
