How do you find the degrees sector of an circle?

It depends on what information you have: the radius and the area of the sector or the length of the arc.


How do you do size of sector?

To determine the size of a sector in a circle, you can use the formula: Area of the sector = (θ/360) × πr², where θ is the central angle of the sector in degrees and r is the radius of the circle. If you have the angle in radians, the formula becomes: Area of the sector = (1/2) × r² × θ. This allows you to calculate the area based on the proportion of the circle that the sector represents.

What is the formula to calculate sector?

A sector is a part of a circle which looks the same shape as a piece of a circular pie. You probably remember that Pi charts look like a circular cake cut into portions. We can calculate the area of the sector of a circle if we know the angle between the two straight sides and the radius of the circle. Now the area of a complete circle is Pi x square of radius, If the radius is 12 cm then the circle's area will be Pi x square of 12 square centimetres. But that is for the full circle. If the sector's angle is 60 degrees, that would mean that the area of the sector would be 60 degrees/360 degrees which equals 1/6; so finally, the area of the sector is (Pi x 12 squared) divided by 6 = 75.398 sq cm )correct to 4 decimal places).


What is the approximate area of the shaded sector in the circle below 18cm?

To find the area of a shaded sector in a circle, you need the radius and the angle of the sector. Assuming the radius of the circle is 18 cm, the area of the entire circle is given by the formula (A = \pi r^2), which equals approximately (1017.88 , \text{cm}^2). If you know the angle of the sector in degrees, you can calculate the area of the sector using the formula (A_{sector} = \frac{\theta}{360} \times A_{circle}), where (\theta) is the angle of the sector. Without the angle, I cannot provide the exact area of the shaded sector.


What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?

Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.

How do you work out the area of a sector when given the length of the arc?

If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
