Answer: 8 centimeters
Step-by-step explanation: To find the radius of the circle, remember that the formula for the area of a circle is πr² and since we're given that the area of our circle is 64π, we can set up the equation 64π = πr².
To solve for <em>r</em>, we first divide both sides of the equation by π.
On the left side, the π's cancel and we're left with 64 and on the right side, the π's cancel and we're left with r².
So we have 64 = r².
Next, we take the square root of both sides to get 8 = r.
So the radius of our circle is 8 centimeters.
I believe question 3 is B and question 4 is B
Answer:
The height is 0 when it "drops".
3/2x + 9 = 0
3/2x = -9
3 = -9(2x)
3 = -18x
3/-18x
Change signs, time cant be negative.
x= 6
Another interpretation; Slope is negative it is falling. This interpretation is more accurate.
-3/2x + 9 = 0
-3/2x = -9
-3 = -9(2x)
-3 = -18x
6 = x

Answer:
Cups of water she needs to make the punch is 12.
Step-by-step explanation:
Amount of water Carson need to make fruit punch = 3 quarts
2 cups is 1 pint
2 pints is 1 quart
1 pint = 1/2 quarts
2 cups is 1 pint which is 1/2 quarts
So, 1 cup:
1 cup is 1/2 times 2 quarts
1 quart is 1 times 2 times 2 cups equals 4 cups
So, 3 quarts equals 3 times 4 cups which equals 12 cups.
So it is 12 cups.
