Question

how many times does a wheel of radius 35cm must rotate to cover a distance of 550 metre​

Answer 1

Answer:

In a round wheel travels equal to its circumference

= 2πr = 2 × 22/7 × 35 = 220 cm = 2.2 m

So rounds to cover 550 m distance

$= \: \frac{550}{2.2} = 250 \: rounds$

Answer 2

250 times a wheel of radius 35 cm must rotate to cover a distance of 550 meter​.

Step-by-step explanation:

To find : How many times does a wheel of radius 35 cm must rotate to cover a distance of 550 meter​ ?

Solution :

Radius r=35 cm

The circumference of wheel is $C=2\pi r$

$C=2\times \frac{22}{7}\times 35$

$C=220\ cm$

Convert into m,

1 cm = 0.01 m

220 cm = 2.2 m

So, 2.2 m cover 1 round

550 m cover in $\frac{550}{2.2}$ round

550 m cover in 250 round

Therefore, 250 times a wheel of radius 35 cm must rotate to cover a distance of 550 meter​.
