Complete area of the circle = 3*66.99 = 200.97 square units
pi*radius2 = 200.97
Divide both sides by pi and then square root both sides
radius = 7.998170905 or about 8 units of measurement
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area

It depends on what else is known about the sector: length of arc, area or some other measure.
The area of the sector of the circle formed by the central angle is: 37.7 square units.
the area of a sector = (angle)/360 x PI x radius x radius pi r squared
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
The area of the sector is: 221.2 cm2
4 ft.
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
394.7841751413609 125.6637061
Radius is 9 so area of complete circle (360o) is 81 x 3.14 ie 254.34. Angle of sector is therefore 360 x 169.56/254.34 which is 240o
Use the formula for the area of a circular sector, and solve for the angle.For a circular sector: area = radius squared times angle / 2 (Note: The angle is supposed to be expressed in radians; and in this specific problem, there is no need to convert it to degrees.) Since you know the area and the radius (according to the comments added to this question), you can solve for the angle. Once you know the angle (in radians!), the arc length is simply angle x radius.
