Radius of a sector of a circle is 3.5 cm and length of its arc is 2.2 cm. Find the area of the sector.
The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and ...
25 Given that the area of a circle with radius 10 cm is equal to the area of a sector with centralangle 40°, then the radius of the sector iscm. 38. Given that the radius of a sector is r, with a central angle of n, the area of thissector is 反馈...
A chord of a circle that has the center in it is referred to as the diameterof a circle. Diameter is the largest chord of a circle that passes through the center of the circle. There is a circle with \(O\) as a centre and \(OP\) as a radius. In the figure, you can see the...
