What is the area of a sector whose central angle is ninety degrees and has a radius of six inches?
Remember that a circle has 360 degrees, and now you are looking for 90 degrees. 90 degrees is 1/4, or a quarter, of 360 degrees. The formula for the area of a sector is [pi(r)^2](x/360), where x is the degrees you are looking for. So the equation is [pi(6)^2](90/360). First, you simplify it to [pi(6)^2](1/4). The next step would be [pi(36)](1/4). The final answer would be 9pi.

What is 2 3rds of a circle?
It depends on the shape that is removed. It could be a smaller circle, whose radius is sqrt(2/3) = 0.8165 of the original radius, Or a circle with a hole with radius sqrt(1/3) = 0.5774 of the original radius cut out of it, Or a wedge making a central angle of 120 degrees removed from the circle, Or more complicated shapes.
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.

What is the measure of the area of a sector of 165 degrees in a disc whose diameter measures 38 meters?
The area of a whole circle is given by π x radius². The sector is a fraction of the whole circle which is the fraction of its angle of a full turn of 360° Thus area_sector = π x (38 m)² x 165°/360° = 3971/6 π m² ≈ 2079 m²
What is the radius of a circle whose circumference is 40 pi?
The radius of a circle whose circumference is 40pi is 20 units.
What fraction of a circle does 7 degrees represent?
It is NOT a fraction but a SECTOR. of 7 degres. The regions of a circle are: - Circumference ; all the way around. Radius ; distance from the centre to the circumference Diameter ; Twice the radius and a straight line from circumference through the centre to the opposite side . Chord; a line drawen inside a circle, betwwen two points on the circumference, but NOT touching the centre. Arc ; that part of the circumference that form the curved side of a sector. Sector ; An area inside the circle whose bondaries are two radii and an arc. Tangent ; a line outside the circle just touching the circumference in ONE place.
