Question

A wheel makes 2000 revolutions in covering a distance of 88 km find the radius of the wheel

Answer 1

If it covers 80km then it's revolutions 2000

then it covers 80/2000 in one revolution

so

80/2000

= 0.04 km

= 0.04×1000 m

= 40m

then we can say that circumference of the wheel is 40 m

circumference = 2πr

40 m = 2×22/7×r

40m = 44/7×r

40m×7/44 = r

6.36 m = r

so the radius of the wheel is 6.36 meter

Answer 2

Answer:

In place of 1000 you can place 2000 and get answers
