Find the area of a sector of a circle with a 2 feet radius formed by a 30 degree angle?
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)
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.
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
How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
A sector of a circle has a central angle of 50 and an area of 605 cm2 Find the radius of the circle?
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
Find the sector area of a sector with radius of 30 and an angle of 60 degrees?
apply this formula: A = t/360 r2 when t = angle at center and r = radius so A = 471.2 (rounded to 1 decimal place)
How do you find the area of a shaded region in a circle?
(pi * radius squared) * ( sector angle / 360 )
How do you find the length of a sector?
The answer depends on what information you do have: radius, arc length, central angle etc.
How do i find the arc length if i know the area?
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.
How do you find the area of a sector of a circle when you're given only the radius and not the degrees?
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
How do you find the angle of sector when arc length isn't given?
By using a protractor and finding the angle between the two radii
How do you find the area of a shaded sector of a sector?
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.
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 the sector area of a circle?
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).
How can you find the angle of a sector in a circle?
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
