Question

the diameter of a wheel is 70 cm . find the distance covered by the wheel in 5 revolutions.​

Answer 1

Answer:2(pi)r = circumference

Step-by-step explanation:

2×22/7×35

=220cm in one revolution

In 5 revolution,

220×5

=1100cm

Answer 2

Answer:

We know that,

No of revolutions =Distance/circumference,

_________________________________________________________

its given that diameter of the wheel is 70 cm,then radius is

d/2=70/2

r=35cm

Circumference =2× 22/7 × 35

Circumference =220cm

__________________________________________________________

By the formula,

5=D/220

D=220×5

D=1100cm

So Distance travelled is 11m
