Answer:
At = 21.5 cm2
Step-by-step explanation:
At = Asqr - Acircle
At = A1 - A2
A1 = 10^2 = 100
A2 = Pi*(5)^2 = 78.5
At = 100 - 78.5
At = 21.5 cm2

Add all her phone bills = 115+43+67+95 =320, divide by how many numbers there are, so 4, 320 divided by 4 = 80
Answer: I believe your answer is C.
Answer: Subtraction property of equality.
Step-by-step explanation:
n + 9 = -3
You are trying to move 9 from one side to the other. To do that, you have to do the <em>inverse operation</em> and <u>subtract</u> nine from both sides. Your result would be n = -12.
Answer:
(0, 5), (0, 1), and (3, 1).
Step-by-step explanation:
If the shape should be rotated about the y-axis to make a cone, then the shape needs to be a right triangle. It will have its length on the y-axis, and the other length either parallel to, or on, the x-axis.
Since we already have a point at (0, 5), we can have another point at (0, 1). That means that the side length is 4. Now, we can make a 3-4-5 right triangle by having another point at (3, 1).
Hope this helps!
