Question

A cycle wheel makes 500 Revolution to cover 220 M find the diameter of the wheel

Answer 1

No of revolutions = 500
Distance travelled = 220m
Distance covered in one revolution = 220÷500
= 0.44 m
Circumference = 0.44 m
$2\pi \: r = 0.44$
$r = \frac{0.44}{2\pi}$
r= 0.7m
Diameter = 0.14 m
=14 cm

Answer 2

Heyy Buddy

Here's your Answer

Given;

Number of Revolutions = 500

Distance Covered = 220 m

Now,

Number of Revolutions = Distance/ Circumference

=> 500 = 220 / x

=> x = 220/500

=> x = 0.44

Circumference = 0.44

$= > 2 \times \pi \times r = 0.44 \\ \\ = > 2 \times \frac{22}{7} \times r = 0.44 \\ \\ = > r = 0.44 \times \frac{7} {22} \times \frac{1}{2} \\ \\ = > r = 0.7$

So,

Diameter = 2 × 0.7

=> Diameter = 0.14 m

=> Distance = 14 cm
