We know that the area of a circle is represented by the equation:
![A=\pi r^{2}](https://tex.z-dn.net/?f=%20A%3D%5Cpi%20r%5E%7B2%7D%20%20)
And we know that the diameter of a circle is twice the radius: ![d=2r](https://tex.z-dn.net/?f=%20d%3D2r%20)
So if we know that the diameter is 13m, we can solve for the radius:
--> ![r=6.5m](https://tex.z-dn.net/?f=%20r%3D6.5m%20)
Then we can plug in this radius into the equation for the area of a circle, using 3.14 to approximate the value of pi:
![A=(3.14)(6.5)^{2}](https://tex.z-dn.net/?f=%20A%3D%283.14%29%286.5%29%5E%7B2%7D%20)
![A=(3.14)(42.25)](https://tex.z-dn.net/?f=%20A%3D%283.14%29%2842.25%29%20)
![A=132.665m^{2}](https://tex.z-dn.net/?f=%20A%3D132.665m%5E%7B2%7D%20%20)
So now we know that the area of the circle is 132.665 square meters.
Answer:
independent
Step-by-step explanation:
, it has no effect on the number of red socks so thewhen he draws out a sock the event is not affected by the draw a blue sock or the bla ck sock or the brown sock
![(x^3+x^2+x+2) divide by (x^2-1)](https://tex.z-dn.net/?f=%28x%5E3%2Bx%5E2%2Bx%2B2%29%20divide%20by%20%28x%5E2-1%29)
We use long division to divide
There is no x term in x^2 -1 so we put 0x
x + 1
----------------------------
x^2+0x-1 x^3+ x^2 + x+ 2
x^3+0x^2-x
-----------------------------(subtract the bottom from top)
x^2 +2x + 2
x^2 +0x - 1
--------------------------------(subtract the bottom from top)
2x + 3
-----------------------------------------
Quotient : x+1
Remainder : 2x+3
Answer:
They are not similar.
Step-by-step explanation:
26 / 13 = 2
24 / 11 = 2.18
They are not proportional which means that they don't have a scale factor and cannot be answered.
