Well when ever you're doing order of operations you always use please excuse my dear aunt sally please means parentheses ALWAYS GO FIRST Excuse means experience which if there's no parentheses exponents go first to my name is multiplication after parentheses multiplication always go first if there's no parentheses dear means division after multiplication comes division on means addition but pretty much after the multiplication parentheses and the division you complete the rest of the problem using the left to right method now the answer to this problem is
Answer:
does the answer help you?
Since the area of a circle is π
![r^{2}](https://tex.z-dn.net/?f=%20r%5E%7B2%7D%20)
, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so:
![c = 360(.6663)](https://tex.z-dn.net/?f=c%20%3D%20360%28.6663%29%20)
≈ 240°
240 degrees
Answer:
![(x+12)^2+(y-5)^2=80](https://tex.z-dn.net/?f=%28x%2B12%29%5E2%2B%28y-5%29%5E2%3D80)
Step-by-step explanation:
First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is
