What is a steradian?
A steradian is the solid angle subtended at the centre of a sphere by radius r by a portion of the surface of the sphere which has area r2.
What type of angle is formed by a tangent and a radius?
The angle between the radius and the tangent is a right angle of 90 degrees.
How do you find the chord length with the central angle and radius?
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
How do you work out the area of a sector using the angle and radius?
the area of a sector = (angle)/360 x PI x radius x radius pi r squared
What angle formed by two radius of a circle?
An angle formed by two radius of a circle? I presume that depends on the inclination of one of the two radius related to the other one.
Definition of solid angle?
solid angle is the ratio of the intercepted area dA of the spherical surface , described about the apex O as the centre ,to square of its radius r

What is the radiance formula used to calculate the brightness of a light source?
The radiance formula is used to calculate the brightness of a light source. It is defined as the power emitted by the source per unit solid angle per unit projected area. The formula is given by radiance (L) power (P) / (solid angle () projected area (A)).
How do you draw an arc with a given length and known radius?
The length of an arc equals he angle (in radians) times the radius. Divide the length by the radius, and that gives you the ange. Measure out the angle on a protractor and draw the length of the radius at the begining and end of the angle. Then draw theportion of the circle with its center at the location ofthe angle and extending out to the radius.

What is a central angle of a circle?
the radius
How do you find the central angle of a circle if I am given the arc length and radius?
(arc length / (radius * 2 * pi)) * 360 = angle
What is the difference between a plain angle and solid angle?
it is same as surface and volume ! a plane angle is 2D and solid angle is 3D
In mathematics in polar coordinates what is the polar coordinates for the point pp on a line makes an angle with the initial line?
the radius vector; and the vectorial angle the radius vector; and the vectorial angle
