Answer:
The correct answer is second option
3π in²
Step-by-step explanation:
<u>Points to remember</u>
Area of circle = πr²
Where r is the radius of the circle
<u>To find the area of outer ring</u>
Here radius of large circle = 1 + 1 = 2 in and
radius of small circle = 1 in
Area of outer ring = Area of large circle - area of small circle
= π2² - π1²
= 4π - π
= 3π in²
The correct answer is second option
3π in²
We can use a factorial for this:
4! = 4*3*2*1 = 24
There are 24 combinations of 4 numbers.

Answer:
It will take 50,000 years to accumulate 5 centimeters of clay.
Step-by-step explanation:
The relationship between millimeter and centimer is that:
1ml = 0.1cm
So
How many ml are 5 cm?
1 ml - 0.1cm
x ml - 5cm
![0.1x = 5](https://tex.z-dn.net/?f=0.1x%20%3D%205)
![x = \frac{5}{0.1}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5%7D%7B0.1%7D)
ml
Clay on the deep seafloor accumulates at a rate of about 1 millimeter per 1,000 years. How long would it take to accumulate 5 centimeters of clay?
5cm is 50 ml.
1 ml per 1000 years.
So
1 ml - 1000 years
50 ml - x years
![x = 50*1000](https://tex.z-dn.net/?f=x%20%3D%2050%2A1000)
![x = 50,000](https://tex.z-dn.net/?f=x%20%3D%2050%2C000)
It will take 50,000 years to accumulate 5 centimeters of clay.
