Question

Wheel makes 500 revolutions in moving 1 km find the diameter of the wheel.

Answer 1

Distance covered= 1km= 1000m.
DIstance / No of revolutions made = Circumference of the wheel
1000 /500 = 2 m = Circumference.
Circumference = 2 * pi * r
2 = 2 * 22/7 * r
r = 7 /22 m.
Diameter = 2r = 2 * 7/22 = 14 /22 = 7 /11 = 0.63 m

Answer 2

so circumference= 1000m÷500=2 m is cirum ference.

Cirumference=2 × pie × radius or diametre×pie

d×22/7=200cm
d=200 ×7/22= 63.63 cm HOPE MY SOLUTION WILL HELP YOU PLEASE MARK ME AS A BRAINLIEST..
