What is the radius of a 90 degree circle?
The radius is a lenght, and it's impossible to find out the radius if you don't give any information about the size of your circle.
What is the radius of a circle?
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
How many degrees are in the arc of a circle?
A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.(another explanation, maybe no better.)A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.
If a diameter of a circle is 25 cm what is the lenght of a radius?
Diameter = 2*Radius. You should now be able to deal with this and similar questions.
How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
How do I measure different parts of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
If An ARC measures 120 degrees what is the length of the radius of the circle?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
What is the radius of a 90 degree circle?
The radius is a lenght, and it's impossible to find out the radius if you don't give any information about the size of your circle.
What is the radius of a circle?
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
What is the Definition of radian measure in maths?
A radian is part of the circumference of a circle and its length is the same size as the circle's radius and it is about 57.3 degrees.
How many degrees are in a circle with radius 4?
There are 360 degrees in any circle. The radius doesn't matter.
How many degrees are in the arc of a circle?

How do you divide a circle into five equal parts?
If a circle is comprised of 360 degrees, then each of the five sections will encompass 72 degrees. From an arbitrary radius, using a protractor, measure 72 degrees, then continue around the circle.
Do Inscribed angles have the same measure as their intercepted arcs?
No they do not unless it is a circle with radius (180/pi) and the angles are measured in degrees, or a circle with radius (1/pi) and the angles are measured in radians.
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
If a diameter of a circle is 25 cm what is the lenght of a radius?
Diameter = 2*Radius. You should now be able to deal with this and similar questions.
The measure from the center of a circle to its edge?
The measure from the center of a circle to its edge is the radius.
