The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)
dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)
Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units
Answer:
I may be wrong but 8 cups of chocolate
Step-by-step explanation:
First I looked over what I needed to do, 1 cup of cream and 2 cups of chocolate.
The next thing I did was attempt to solve it in 2 different ways, the first one being adding 1 cup of cream and 2 cups of chocolate every time, but that didn't work. The second attempt I just kept 1 cup of cream and added 6 cups of chocolate.
I added 6 because there are already 2 cups of chocolate, so that would add up to 8 cups. We didn't add any cups of cream so its still one. 8+1 is obviously 9.
Sorry if I am wrong
In the question , the length of the actual rope is given as 40 foot. Also it is given that the length of one rope after cutting the original piece of rope into 2 pieces is 9 times that of the other pice.
Let us assume that the length of one piece of rope is = X
Then the length of the orther pice of rope = 9X
Now we can easily get the equation
X + 9X = 40
10X = 40
X = 40/10
X = 4
So the length of the shorter rope is 4 foot.
The length of the longer rope is 9 times that of the shorter one.
So the length of the longer rope is 36 foot.

Answer:
7/2 =x
Step-by-step explanation:
The triangles are similar so we can write a ratio to solve
2 4
---- = -------
x 7
Using cross products
2*7 = 4x
14 = 4x
14/4 = 4x/4
7/2 =x
