It depends on what information you have: the radius and the area of the sector or the length of the arc.
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
You cannot. The angle of the sector MUST be given, although that might be implicitly rather than explicitly.
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians. In this case, the central angle is 400 degrees, which is approximately 6.98 radians. Plugging in the values, we get 300 = 0.5 * r^2 * 6.98. Solving for r, we find that the radius is approximately 7.67 cm.
To find the radius of a circle from a central angle of 120 degrees, you need additional information, such as the length of the arc or the area of the sector. If you have the arc length (s), you can use the formula ( r = \frac{s}{\theta} ), where ( \theta ) is in radians (120 degrees is ( \frac{2\pi}{3} ) radians). If you know the area of the sector, you can use ( r = \sqrt{\frac{A}{\frac{1}{2} \theta}} ), where ( A ) is the area and ( \theta ) is in radians. Without extra data, the radius cannot be determined solely from the angle.
