How do you find the measurement of an arc or angle on a circle?
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
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.
How do you find the arc in a sector?
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
What is the formula for finding the arc length of a circle?
angle of the circle/360 x 2(pi)r
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 do you find the measurement of an arc or angle on a circle?
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
To find arc length what do you need to multiply a circle's circumference by?
the fraction of the circle covered by the arc
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.
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)
How do you find the arc in a sector?
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
How do you find arc of an circle when the degrees is given?
It depends on what measure related to the arc you want to find!
What is the formula for finding the arc length of a circle?
angle of the circle/360 x 2(pi)r
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 would you find the fraction of a circle that an arc covers?
divide the measure of the arc by 360
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.
What is the formula for the measure of an arc?
The length of an arc of a circle of radius r, which subtends an angle of x radians at the centre is r*x.
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
