Abicycle wheel with the diameter 70cm is making 25 revolutions while travelling. find the distance covered by the bicycle

5500cm.

Step-by-step explanation:  

A revolution  corresponds to circumference of the bicycle wheel.

The radius of the circle = 70/2 since two radii makes a diameter.

Therefore r = 35cm

Circumference of a circle =  2πr or πd where π = 3.142 or 22/7

      We now have              =  2 x 22/7 x 35

Therefore 0ne revolution   = 220cm.

Therefore, the distance traveled by making 25 revolution

                                            = 220 x 25

                                            = 22000/4

                                            = 5500cm.

10 you would take 50/ .2
