Let the arc is ABC with angle 324 degree, to find the length of that arc follow the steps;
The circumference of the circle E is :C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180
= 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
The equation is
(y-2)/(x-(-1))=-6
y-2=-6x-6
y=-6x-4
Answer:
y = 34, then the equation is true.
Step-by-step explanation:
This is because if the square root of a number is multiplied by itself, you are essentially squaring a square root, which cancels out.
