Question

the diameter of a wheel is 28cm . how many revolutions will it make to travel 352m​

Answer 1

Step-by-step explanation:

As we know that the distance travelled in one revolution is equal to the circumference of the wheel which is given by 2πr. Hence, to make one revolution the wheel has to travel 88 cm.

Answer 2

Answer:

Firstly find the circumference

So circumference will be 22/7 * 28

=88

Now divide the length of path by circumference

So, 352/88=4

So ur answer will be 4

Circumference of a circle is also equal to πd

As d=2r
