Question

The diameter of bicycle wheel is
70CM find how many times the
wheel will revolve
in order to
cover a distance of 154 m (Take= 22/7​

Answer 1

Answer:

calculate the parameter of a wheel

p=2πr

r=35cm

p= 2*(22/7)*35

p=220cm

distance =154m =1540cm

n is number of time wheel revolve

n= 1540/220

n= 7 times

Answer 2

Answer : 70 times ✔✔

______________________________

Solution :

Let, n times the wheel will revolve in order to cover a distance.

As we know that :

Circumference of a circle = 2πr, where r is a radius of circle

Then, According to the question :

$n \times 2\pi \: r = 154$

Here, diameter of wheel = 70cm

Then, Radius of wheel = 70/2 cm => 70/2×100 m = 0.35m

$= > n \times 2 \times \frac{22}{7} \times 0.35 = 154 \\ \\ = > n = \frac{154 \times 7}{2 \times 22 \times 0.35} \\ \\ = > n = 70$

So, wheel will revolve 70 times in order to cover the distance.
