the radius of a wheel is 3 cm. what is the distance travelled by it in 15 revolution?
Distance travelled in one revolution
= 2 × π × r
where r is 3 cm.
Distance travelled in 15 revolutions will be 15 time the above amount.

To calculate the distance traveled by a wheel in 15 revolutions, we need to know the circumference of the wheel.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * Radius
Given that the radius of the wheel is 3 cm, we can calculate the circumference:
Circumference = 2 * π * 3 cm
Circumference = 6π cm
Since we want to find the distance traveled in 15 revolutions, we need to multiply the circumference by the number of revolutions:
Distance Traveled = Circumference * Number of Revolutions
Distance Traveled = 6π cm * 15 revolutions
Distance Traveled = 90π cm
Therefore, the distance traveled by the wheel in 15 revolutions is 90π cm.
