Question

Find the distance covered by the wheel of a car in 500 revolution if the diameter of the wheel is 77 cm
​

Answer 1

answer

the diameter of wheel is 77 cm

circumference = πd

circumference = 22/7 * 77

we will cancel 77 by 7 to get 11

so, circumference = 22*11

circumference = 242cm

so, distance travelled in i revolution of wheel is 242 cm

so, distance covered in 500 revolutions = 242*500

= 121000 cm

= 1.21 km

or 1 km 210 m

hope it helps

have a nice day
