Circumference of circle: 360/21 times 25 = 3000/7
Radius of sector: (3000/7) divided by (2*pi) = 68 units to the nearest integer

How do you find radius using angle of a sector?
It depends on what else is known about the sector: length of arc, area or some other measure.
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
Find the arc length of the minor arc if the radius is 13 and the sector is 85?
19.28
What is the length of an arc corresponding to an angle of one radians?
Equal to the length of the radius.
How do you find the radius of a circle if the central angle is 36 degrees and the arc length of the sector is 2 pi cm?
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
If a sector has an angle of 118.7 and an arc length of 58.95mm what is its radius?
If a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm
How do you find the length of a sector?
The answer depends on what information you do have: radius, arc length, central angle etc.
What is the relation between area of a sector and length of an arc of a circle?
There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
What is the area of the shaded sector with a radius of 7?
That will depend on the length or angle of the arc which has not been given
What is the radius of the sector with an angle of 27 degrees and arc of 12cm?
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
Find the arc length of a sector with a radius of 30 and an angle of 60 degrees?
arc length = angle/360 x r 60/360 x 30 = 5
How do you find radius using angle of a sector?
It depends on what else is known about the sector: length of arc, area or some other measure.
What is the arc length of a sector that is 125degrees and has a radius of 20 inches?
The arc length of a sector that is 125 degrees and has a radius of 20 inches is: 43.63 inches.
How do you calculate the the arc of a sector?
To calculate the arc length of a sector: calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees) so : (pi * diameter) * (sector angle / 360) = arc length
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 measure sector angles?
s=r x theta s=arc length r=radius theta=angle
