Question

the distance travelled by a circular wheel of diameter is D cm in one revolution and it is equal to _____cm​

Answer 1

Answer:

The revolution of the circular wheel is measure by the circumference of the wheel. So, i.e. the distance traveled by a circular wheel of diameter d cm in one revolution is cm. Therefore, the given statement is not true.

Answer 2

Given,

The diameter of the circular wheel = D cm

To find,

The distance travelled by the wheel in one revolution.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now, any circular wheel covers a distance equal to its own circumference, in one revolution.

So, we need to calculate the circumference of the given circular wheel, in order to get the distance travelled by the circular wheel in one revolution.

Radius of the circular wheel = Diameter/2 = (D/2) cm

Circumference of the wheel = 2 × π × radius = 2 × π × (D/2) = πD cm

Which means, distance travelled in one revolution = πD cm

Hence, the distance travelled by a circular wheel of diameter is D cm in one revolution is equal to πD cm.
