180 I think not sure if I am right
Its 15% because you have to divide 270 by 1800
The equation for a circle is (x-h)^2 +(y-k)^2=r^2
You just have to plug in your coordinates h is the x and k is the y.
The r is radius squared.
so, (x-2)^2+(y-(-5)^2=144
You have to be careful of those tricky negative values. When you distribute the y-(-5) it turns into y+5.
So your answer is D.
For 61 you can change it to √25/√49. √25=5 and √49=7 so it would simplify to 5/7.
Answer: 81 - 74 = 7
Have a great day!
