Question

The diameter of a wheel of a car is 77cm .find the distance covered by car in 500 revolution

Answer 1

Answer:

Step-by-step explanation:

RADIUS OF WHEEL= 77/2 CM

DISTANCE COVERED IN ONE REVOLUTION =

                          =2*22/7*r

                          =2*22/7*77/2

                        =242 CM

DISTANCE COVERED IN 500 REVOLUTIONS = 242*500

                                                                             =121000CM

                                                                               =1210M ANS

Answer 2

Answer:

Step-by-step explanation:

As

D= 77 cm

∴ R = D/2 = 77/2 cm  

Distance covered in 1 revolution is equal to circumference of the wheel

i.e.  2πR

so

distance  in 500 revolution = 500 × 2πR

                                              =  500×2×22/7×77/2 cm

                                             = 121000 cm

                                             = 1210m or 1.21 km
