the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi) the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi)
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.
(arc length / (radius * 2 * pi)) * 360 = angle
19.28
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
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
apply this formula: A = t/360 r2 when t = angle at center and r = radius so A = 471.2 (rounded to 1 decimal place)
(pi * radius squared) * ( sector angle / 360 )
The answer depends on what information you do have: radius, arc length, central angle etc.
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.
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
By using a protractor and finding the angle between the two radii
The area is r^2*x where r is the radius of the circle and x is the angle measured in radians. If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.
The area of a sector is 0.5*r^2*theta square units where r is the radius measured in linear units and theta is the angle (measured in radians).
arc length = angle/360 x r 60/360 x 30 = 5
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
