the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle

The length of an arc is the radius times the angle in radians that the arc subtends length = radius times angle in degrees times pi/180

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

Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)

you need to know the formula the arc length is equal to the radius times the angle made by the length of arc s = r(theta) s=arc length r=radius theta=angle

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

(arc length / (radius * 2 * pi)) * 360 = angle

the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle

it is more accurately called the "arc" the arc in circles are measure by the radius and the angle of projection. the formula is... s=r(angle) s is the arc length r is the radius length angle is the angle that the entire arc length makes

If a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm

The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).

Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)

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.

If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?

angle of arc/ angle of circle (360°) = length of the arc/ total circumference (2 pi* radius) so you just have to find r then so: angle of arc/ angle of circle (360°) *2pi = length of the arc/ radius radius= ength of the arc/ angle of arc/ angle of circle (360°) *2pi not that hard ;)
