6. Find the area of the segment of a circle, if angle of
the sector is 90° and the radius of the circle is 21 cm.​

Answer 1

Answer:

346.5 cm^2

Step-by-step explanation:

Area of segment is πr²α/360, where r is the radius and α is angle of sector.

Area = (22/7) x (21x21) x (90/360) = 22 x 3 x 21 / 4 = 346.5 cm^2
