164
Inscribed angle=.5 arc
82=.5arc
Arc=164
All sides are equal in an equilateral triangle and the perpendicular bisects the side too.
so BC will be bisected and the segments be 5 each.
you can use Pythagoras theorem to find the altitude length, hypotenuse will be one side of the triangle.

$h^2=100-25=75$
$h=\sqrt{75}=5\sqrt3$
A- Since the radius is 22, the area is 1520.53, or, 1520.5 simplified.
Answer:
I'm jus gonna guess 94 if right brainliest plzzz
