Question

if the radius of a wheel is 34 cm, how far will the week cover by one complete round?​

Answer 1

Answer:

the wheel covered by one complete round is 213.52 cm

Step-by-step explanation:

one complete round means perimeter of the wheel.

here raditya is 34 cm

perimeter =2* π*radius cm

=2*3.14*34 cm

=3.14*68 cm

=213.52 cm

Answer 2

Given :

The radius, r of the wheel is  34 cm.

To Find :

We have to find the distance covered by the wheel in one rotation.

Solution:

The distance around the circle is known as the circumference of a circle. This is also how far the circle rolls on flat ground in one complete rotation.

∴ One revolution of a wheel makes it move a distance equal to its circumference.

∴ The circumference of a circle is given by,  

                                                 $\[C = 2\pi r\]$

                                                     $\[\begin{array}{l} = 2 * \pi * 34\\\\ = 213 \cdot 63\,cm\\\\ = 2 \cdot 13\,m\end{array}\]$

Hence, the distance covered by the wheel in one rotation is equal to 2·13 m.
