Answer:
C) 188.4 cm
Step-by-step explanation:
In order for you to know how far a wheel travels in 3 revolutions, you need to know the circumference of it. A revolution equals the value of the circumference.
The formula to obtain the circumference of the circle is:
<em>π * diameter</em>
Moreover, to obtain the diameter, you need to multiply the radius times 2.
Therefore,
<em>π * 2 (radius) = π * 2(10)</em>
<em>π * (20) = 62.8 </em>
The circumference of the circle is 62.8 cm.
Then,
<em>3 * 62.8 = </em><em>188.4</em>
