Answer:
x = -3 and x= 3
Step-by-step explanation:
2,
is the Y intercept of that equation
The area of a circle is pi*r^2.
The angles in a circle add up to 360 degrees.
Let's say I have a circle with radius 2.
The total area of the circle is pi* (2^2) = 4pi
Let's say I cut out 15 degrees of this circle. This piece is 15 out of 360 of the whole circle.
The area of this part is (15/360) * 4pi
The rest of the area is (360-15)/360 * 4pi.
I hope this helps.
The formula for a circle is (x-h)^2 + (y-k)^2 = r^2 where h is x-value and k is the y-value of the center.
If diameter is 24, the radius is 12
(x + 9)^2 + (y - 5)^2 = 144
