<h2>Hello!</h2>

The answer is:

The difference between the areas of the circles will be:

Difference=36\pi -9\pi =27\pi

<h2>Why?</h2>

To find the diffence in area between the two circles, we need to find both areas and then, subtract the smallest circle area to the largest circle area.

So,

For the small circle, we have:

Area_{SmallCircle}=\pi *radius^{2} \\\\Area_{SmallCircle}=\pi *(3)^{2}=9\pi

For the large circle, we have:

Area_{LargeCircle}=\pi *radius^{2} \\\\Area_{LargeCircle}=\pi *(6)^{2}=36\pi

Hence, we have that the difference between the areas of the circles will be:

Difference=36\pi -9\pi =27\pi

Have a nice day!

Answer:

Difference = 27π square units

Step-by-step explanation:

Points to remember

Area of circle = πr²

Where r - Radius of circle

<u>To find the area of large circle</u>

Here r = 6 units

Area = πr²  = π * 6²

 = 36π square units

<u>To find the area of small circle</u>

Here r = 3 units

Area = πr²  = π * 3²

 = 9π square units

<u>To find the difference </u>

Difference = area of large circle - area of small circle

 = 36π - 9π = 27π square units

A family drive 50 mph to Disneyland and return home at 40mph find the distance if the total driving time was 7.2 hours?
Neko [114]
First, let's initialize a variable called 'h' that will represent the number of hours it took to drive to Disneyland (you could do from if you wanted, in the end it doesn't really matter)

Since we know that the distance there and back is the exact same, we can make the following equation:
50(h) = 40(7.2 - h)

We know we can write this equation because rate multiplied by time is distance. We also know that the time to come back is 7.2 minus h, since h represents the time going there.

Simplify:
5(h) = 4(7.2 - h)
5h = 28.8 - 7h
12h = 28.8
h = 2.4

Now that we have the time it took to drive there, we can simply multiply it by the rate to find distance:

50*2.4 = 120

The distance to Disneyland is 120 miles.

If you need me to explain anything here, just ask :)
