Find the area of a sector of a circle with radius 6 cm if angle of the sector is 60°.
Sector & Segment. A sector is a part of a circle surrounded by two radii of it together with their intercepted arc. The segment is that region that is enclosed by a chord together with the arc subtended by the chord. Common Sectors. In geometry, Quadrant and Semicircle are known as two special versions of a sector.

(i) The perimeter of a sector of a circle is 58 cm. Find the area if its diameter is 9 cm. (ii) Find the area of a sector whose radius and perimeter are 20 cm and 110 cm respectively.
Jul 6, 2018 · measure of the angle of sector = 90° Radius of circle = 7 cm. We have to calculate the perimeter of sector which is a part of circle. We know that, perimeter of circle = 2.π.r. So, we can write the perimeter of sector of circle which forms a angle of 90° at the center. cm = 10.99 + 14 cm = 24.99 cm
