How do I find the diameter of a circle only having an arc length?

If you have only the arc length then you cannot find the diameter.


How to find a sector area in a circle if you have only the arc length?

If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.


What is the arc length if the length of the arc is 95 degrees?

Find the circumference of the whole circle and then multiply that length by 95/360.


What is the arc in a circle that is 90 degrees?

To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).


How do you find the circumference and arc length of a circle?

It depends on what information you do have.


How would your find the fraction of a circle that an arc covers?

Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)


What is the length of an arc of a circle?

The length of an arc of a circle refers to the product of the central angle and the radius of the circle.


How can you find the length of an arc with the radius known?

The length of the arc is r*theta where r is the radius and theta the angle subtended by the arc at the centre of the circle. If you do not know theta (or cannot derive it), you cannot find the length of the arc.


How do you find radius of a circle if given arc length?

you will need to know the angle subtended by the arc; arc length = radius x angle in radians


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


How do you find the arc ABC length 120 degrees 10?

An arc length of 120 degrees is 1/3 of the circumference of a circle
