What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
How do you find the formula for are of triangle?
the formula for the arc of a triangle is the arc length is equal to the angle times the radius. s=arc length theta=angle made y length of the arc lenth r=radius s=theta times radius

What is the curvature of circle having radius a?
1/aAccording to Wikipedia,"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
Can the focal length of a lens be equal to its radius?
Radius of cuvature = 2 x focal length So both cannot be equal in any way
What is the length of an arc corresponding to an angle of one radians?
Equal to the length of the radius.
Why do images in a concave mirror appear inverted?
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
Is this statement true or falseThe side length of a regular hexagon is equal to the length of the radius?
true
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
Does the radius of a circle equal the length of a side a hexagon inscribed in the circle?
Yes.
