What is the radius of a circle when you only know the arc length of 18.75 of a segment a b c with a degree of 72 degrees a to c in the segment?

The arc represents 1/5 of the circumference (72 = 360/5) so the full circumference is 5 x 18.75 ie 93.75, which is 2 pi x the radius. The radius is therefore 46.875/pi, just over 14.9.

How do you find the circumference of a circle that has an arc length and angle degree?
The total circumference is (arc length) times (360) divided by (the angle degrees)
How do you construct a circle that has radius with an equal length to the given line segment?
Adjust the compass to the given line segment then construct the circle.
A segment joining the center of a circle to a point of a circle?
That's a radius of the circle. Its length is 1/2 of the circle's diameter.
Both the red and blue line segments stretch from the center of the circle to a point on the circle The length of the blue line segment is 17?
Every line segment between the center of a circle and any point on the circleis the same length as all the others.That length is called the 'radius' of that particular circle.
What is the length of the segment connecting two radii in a circle?
The diameter STUPID!
A line segment that connects the center of a circle to a point on the circle?
what about such a line segment? the length of such a segment is called the radius. the area of the circle is pi*the length of this segment squared the circumference is 2*pi*the length of this segment
Given a circle with a radius of 8mm and an arc with a length of 4.2 mm what is the degree of the arc?
The degree of the arc is: 30.08 degrees.
How do you find the radius of a circle if you know the segment?
if the segment is the whole length of the circle divide it by 2
What is a line segment with one endpoint at the center of a circle and the other endpoint on the circle or the length of that segment?
The line segment is a radius.
Segment that has one endpiont at the center and the other endpoint on the circle?
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
How do you find the degree of an arc with the given length?
say a circle's degree is 360. and cut it in half to make an ark. that would 180 degrees?
How do you find the circumference of a circle that has an arc length and angle degree?
The total circumference is (arc length) times (360) divided by (the angle degrees)
How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
How do you construct a circle that has radius with an equal length to the given line segment?
Adjust the compass to the given line segment then construct the circle.
Both the red and blue line segments stretch from the center of the circle to a point on the circle The length of the blue line segment is 7 How long is the red line segment?
If it is a circle and not an oval, they should be the same length. 7.
A segment joining the center of a circle to a point of a circle?
That's a radius of the circle. Its length is 1/2 of the circle's diameter.
Length of circle?
360 degrees
