The wheel of a compact car has a 25-in. diameter. the wheel of a pickup truck has a 31-in. diameter. to the nearest inch, how much farther does the pickup truck wheel travel in one revolution than the compact car wheel?

6 in.
9 in.
19 in.
38 in.

Option C. 19 in.

Step-by-step explanation:

The wheel of a compact car has a diameter = 25 in. and the wheel of a pickup truck has 31 in. diameter.

We have to calculate the difference in the distance covered by each wheel in one revolution.

As we know distance covered by each wheel in one revolution is equal to its perimeter.

So bigger wheel will cover more distance as compared to the smaller one because bigger wheel will have more perimeter than smaller one.

Now perimeter of the wheel of a pickup truck = 2πr = 2π(31/2) = 31π in.

Perimeter of the wheel of a compact car = 2πr' = 2π(25/2) = 25π in.

Now the difference will be = 31π - 25π = 6π = 6×3.14 = 18.84 in. ≈ 19 in.

Answer will be option C. 19 in

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
