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