Answer:
( x +2)² + ( y - 4)² = 81
Step-by-step explanation:
The equation for a circle in standard form is ( x – h)² + ( y - k)² = r², where the center is (h, k) and the radius is r.
Putting the question's given information into the formula gives you
[ x – (-2)]² + ( y - 4)² = (9)²
( x + 2)² + ( y - 4)² = 81
Answer:
Arc Length = 40
Step-by-step explanation:
Arc Length Formula: S = rΘ
R = radius
Θ = Radians
<u>Step 1: Identify the radius and the radian angle</u>
R = 8
Θ = 5 radians
<u>Step 2: Plug into the equation</u>
S = (8)(5)
<u>Step 3: Solve</u>
S = 40
Answer: Arc Length = 40
the picture in the attached figure
we know that
in the right triangle FON
sin F=opposite side angle F/hypotenuse
in this problem
opposite side angle F=ON--------> 9 units
Hypotenuse=FN--------> 18 units
so
sin F=ON /FN-------> sin F=9 /18
therefore
the answer is the option
B.) sin F 9/18
