Answer:

1017.36 square miles

Step-by-step explanation:

Since the diameter of a circle is twice the radius, the radius of this circle is 36/2=18. Since the area of a circle is $\pi r^2$ , the area of this circle is:

$3.14 \cdot 18^2 = 1017.36$

Hope this helps!

If the blue radius below is perpendicular to the green chord and the segment

IgorLugansk [536]

Answer:

O B. 17 units

Step-by-step explanation:

The chord is AC and the radius of the circle is perpendicular to the chord at B. AB = 8.5 units. According to the perpendicular bisector theorem, if the radius of a circle is perpendicular to a chord then the radius bisects the chord. This means that chord AC is bisected by the radius of the circle at point B. The length of the circle is calculated using:

$AB=\frac{AC}{2}\\ AC=2*AB\\cross multiplying:\\AC = 2*8.5\ units\\AC = 17 \ units$

The length of the chord is 17 units.
