Question

a cycle makes 1000 revloution in moving 880m find diameter of wheel

Answer 1

Given, Cycle makes 1000 revolutions moving = 880 m

So,

Cycle makes 1 revolution moving = 880/1000 = 88/100 m

1 revolution of cycle is the circumference of the wheel.

Circumference of the wheel = 2πr (where r is the radius)

2πr = 88/100

2 * 22/7 * r = 88/100

44/7 * r = 88/100

r = 88*7 / 4400

r = 14/100

r = 7/50

r = 0.14 m

Diameter = 2 x r = 2 x 0.14 = 0.28 m

hence our diameter of the wheel = 0.28 m
