Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees




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)

if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector


What is the radius of a circle if it had a 90 degree sector and an area if 64pi?

From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].


Find the area of the sector when the sector measures 10 degrees and the diameter of the circle is 12?

For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.


What is the radius of the sector with an angle of 27 degrees and arc of 12cm?

The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm


The area of the sector formed by the 110 degree is 50 units what is the radius of the circle?

If you mean a sector with an arc of 110 degrees and an area of 50 square units Area of all the circle: 360/110 times 50 = 163.'63' square units Radius of the circle is the square root of 163.'63'/pi = 7.2171377402 So the radius of the circle is about 7 units


Find the area of a 120 degree sector of a circle with a radius of 6?

There are 360 degrees in a circle so it will be 1/3 of pi*62 square units

What is the area of the shaded sector of a circle when the radius is 3?

0. There is no circle so no shaded area of a circle!


What us the answer to the sector if the radius was 6cm and the angle was 120 degrees?

The sector isn't a question, and there's no answer to it. There are a fewnumbers that describe it, however, and they can be calculated like this:-- The circumference of the circle is (pi) x (diameter) = 12 pi cm-- The area of the circle is (pi) x (radius)2 = 36 pi cm2-- 120 degrees is 1/3 of the circle.The length of the arc of the sector is 12 pi/3 = 12.5664 cm (rounded)The area of the sector is 36 pi/3 = 37.6991 cm2(rounded)


What is the radius of circle with an area sector of 662.89?

The area of a circle is derived from Pi x r2 where Pi = 3.14 and r = the radius, therefore a circle with an area of 662.89 has a radius of 14.5
