Awheel has a radius of 12 cm. approximately how far does it travel in 2 revolutions?

47.1 cm

150.72 cm

188.4 cm

376.8 cm

Option B is correct

150.72 cm far does it travel in 2 revolutions

Step-by-step explanation:

Using the formula:

where

D is the distance

n is the number of revolution

r is the radius of the circle.

As per the statement:

A wheel has a radius of 12 cm.

⇒cm

We have to find the distance does it travel in 2 revolutions.

Substitute the value of n = 2 , r =12 cm and we have;

Simplify:

cm

Therefore, 150.72 cm far does it travel in 2 revolutions

sine

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
