Question

when a cyclist rides a cycle, the wheel of the cycle having radius 77cm makes 500 revolution in 5 minutes. Find the speed of the cycle in km per hour.​

Answer 1

Answer:

17.424 KM/Hr

Step-by-step explanation:

Answer 2

Answer:

Radius of the wheel = 77cm

It's circumstances

$\large \mid \blue {=2\pi \: r }$

$\large \mid \blue{(2 \times \frac{22}{7} \times 77) cm}$

$\large \mid \blue{484cm}$

Now distance covered by the wheel in 1 revolution= 484cm

Distance covered by the wheel in 500revolution = (484 × 500)cm = 242000cm = 2.42cm

Distance covered in 5 minutes = 2.42cm

Distance covered in 1 hour (60min)

= ($\frac{2.42}{5}$ × 60) km

= 29.04km
