The percentage of your savings that I use is 60%
This shows that the amount of money the organization will raise in total is $25,000.
1) Given
Total amount saved = $4500
Amount used = $2,700
Percentage of money used = Amount used/Total amount saved × 100%
Percentage of money used = 2700/4500 × 100%
Percentage of money = 27/45 ×100
Percentage of money used = 2700/45
Percentage of money used = 60%
Hence the percentage of your savings that I use is 60%
2) Let the amount of money the organization will raise in total be x
Since the 45% of the money they raise represents $11,250, hence:
45% of x = $11,250
0.45x = 11,250
x = 11,250/0.45
x = 25,000
This shows that the amount of money the organization will raise in total is $25,000

In the
plane, we have
everywhere. So in the equation of the sphere, we have
![25=(x-2)^2+(y+10)^2+(-3)^2\implies(x-2)^2+(y+10)^2=16=4^2](https://tex.z-dn.net/?f=25%3D%28x-2%29%5E2%2B%28y%2B10%29%5E2%2B%28-3%29%5E2%5Cimplies%28x-2%29%5E2%2B%28y%2B10%29%5E2%3D16%3D4%5E2)
which is a circle centered at (2, -10, 0) of radius 4.
In the
plane, we have
, which gives
![25=(x-2)^2+10^2+(z-3)^2\implies(x-2)^2+(z-3)^2=-75](https://tex.z-dn.net/?f=25%3D%28x-2%29%5E2%2B10%5E2%2B%28z-3%29%5E2%5Cimplies%28x-2%29%5E2%2B%28z-3%29%5E2%3D-75)
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the
plane,
, so
![25=(-2)^2+(y+10)^2+(z-3)^2\implies(y+10)^2+(z-3)^2=21=(\sqrt{21})^2](https://tex.z-dn.net/?f=25%3D%28-2%29%5E2%2B%28y%2B10%29%5E2%2B%28z-3%29%5E2%5Cimplies%28y%2B10%29%5E2%2B%28z-3%29%5E2%3D21%3D%28%5Csqrt%7B21%7D%29%5E2)
which is a circle centered at (0, -10, 3) of radius

Answer:
Given the statement: Crater Lake in Oregon in shaped like a circle with a diameter of about 5.5 miles.
Area of circle is given by:
![A = \pi \frac{d^2}{4}](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20%5Cfrac%7Bd%5E2%7D%7B4%7D)
where
A represents the area of a circle
d represents the diameter of a circle.
then;
It is given that Surface of Crater lake is shaped like a circle.
Substitute the given values, we have;
Area of a circle = ![\pi \frac{(5.5)^2}{4}](https://tex.z-dn.net/?f=%5Cpi%20%5Cfrac%7B%285.5%29%5E2%7D%7B4%7D)
=
square miles
therefore, the area of a surface of a crater lake is, 23.74625 square miles.
No, because the divisor may not divide evenly.
