Answer:
Option B is correct
150.72 cm far does it travel in 2 revolutions
Step-by-step explanation:
Using the formula:
\(D = n ( 2\pi r)\)
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.
⇒\(r =12\)cm
We have to find the distance does it travel in 2 revolutions.
Substitute the value of n = 2 , r =12 cm and \(\pi = 3.14\) we have;
\(D = n ( 2\pi r)\)
\(D = 2 \cdot (2 \cdot 3.14 \cdot 12)\)
Simplify:
\(D = 150.72\) cm
Therefore, 150.72 cm far does it travel in 2 revolutions
