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 =12cm

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

To determine this, we need to set up proportions.
x/100 = 75/500.
A quick way to find x, the percentage we're looking for, is to cross multiply our fractions.
100 x 75 and 500 with x.
75 x100 = 7500, and 500 times x is 500x.
7500=500x
Divide by 500 on each side.
15 = x
Your answer is C.)15%.
I hope this helps!
