A circle is a path traced by a point that is equidistant from a unique point on the plane, this point is called the centre of the circle and the constant distance is called the radius of the circle. Any diameter of a circle cuts it into two equal semicircles. (This is called Thales the measure of the intercepted arc is 180 degreesor half the total of 360 degrees in a circle. Half of the circle is called the semi circular arc. When the central angle formed by the two radii is 90 90 , the sector is called a quadrant (because the total circle comprises four quadrants, or fourths).

The sector of a circle is formed by two radii meeting at a central point. When length of the arc ( l) is given, then area of sector. The remaining portion of the circle is called a major arc as it is more than 180 degrees. Of the 39 new therapies expected to launch by 2026 globally, more than half will be their companys first. A sector is said to be a part of a circle made of the arc of the circle along with its two radii. The curved side, part of the circumference of the whole circle, is called an arc. Answer (1 of 7): A part of a circle enclosed by its two radii and arc intercepted by them is called a sector. Anytime you cut a slice out of a pumpkin pie, a round birthday cake, or a circular pizza, A sector with the central angle of 180 is called a half-disk and is bounded by a diameter and a semicircle.

Area of Circle Formula.

A sector of a circle is the region enclosed by the central angle of a circle and the circle itself. Anytime you cut a slice out of a pumpkin pie, a round birthday cake, or a circular pizza, A sector with the central angle of 180 is called a half-disk and is bounded by a diameter and a semicircle.

I agree with your calculations for the area of the quadrant sector and for the areas of the two parts in which the sector is cut by the chord A B, namely, the triangle A O B and the remaining part A D B P, which is called a circular segment.

the centre of the circle, whereas a major sector has no angle. For example, the area A of a circle is the multiplication value of R2. A secant line intersects the circle in two points. A circle is a collection (set) of all those points in a plane, each one of which is at a constant distance from a fixed point in the plane. Math.

Curiously, the answers all missed the most obvious 6-p

Perimeter of sector = 2 radius + arc length. sector OACB is the major sector. The ratio of the area of a sector of a circle to the area of the whole circle (pi r ^2) is equal to the ratio of the measure of the intercepted arc to 360 Sector. A sector is the area covered by two radii and a minor arc and or major arc.
