how many times does a wheel of a radius 28 cm rotate to go 5.28 m
Answers
Step-by-step explanation:
circumference of wheel = 2πr
= 2 × 22/7 × 28
= 176 cm
Wheel can rotate to go 528 cm = 528/176
= 3 times
So, wheel rotate 3 times to reach at a distance of 528 cm or 5.28 m
hope it helps you :)
Given : a wheel of radius 28 cm rotate to go 5.28 m
To Find : How many times does wheel rotates
Solution:
a wheel of radius 28 cm
Circumference = 2πR
π = 22/7
R = 28 cm
=>Circumference = 2(22/7) * 28
= 44 * 4
= 176 cm
Hence in one rotation wheel covers = 176 cm
Distance to be covered = 5.28 m
1 m = 100 cm
=> Distance to be covered = 528 cm
Number of rotations required = 528 / 176
= 3
3 times a wheel of radius 28 cm rotate to go 5.28 m
