101.6 degrees = 1.7733 radians.
So arc = radius*angle (in radians) = 219/2*1.7733 = 194.2 ft.
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.

The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
The area of the sector of the circle formed by the central angle is: 37.7 square units.

May things, but the probable answer sought here is a diameter of a circle, at the circumference of the circle.
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.

An angle subtended at the semicircular arc is 90 degrees.
A circle has 360 degrees, whatever its diameter.
It is 360 degrees because angles around a point add up to 360 degrees
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
There is not enough information to answer the question. You need the radius (or diameter) of the circle.
If a triangle is drawn in a circle with a diameter as the base of the triangle, then the angle opposite that diameter is a right angle. This is an extension of the theorem that the angle which an arc of a circle subtends at the centre of a circle is twice the angle which the arc subtends at the circumference. In the case of a diameter, then the angle subtended at the centre is 180° and thus the angle at the circumference is 90°.
diameter = circumference/pi
