Question

A wheel has a radius of 12 cm. Approximately how far does it travel in 2 revolutions?

Answer 1

150.72 cm is your answer 

Answer 2

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
