Question

The measure of a central angles of a circle is 150°and radius of the circle is 21 cm. find area of the sector associated with the central angle.​

Answer 1

Answer:

577.50cm2

Step-by-step explanation:

Central angle= 150 degree

radius= 21cm

length of arc= x2πr/360

= 150x2x22x21/360x7 = 55cm

length of arc=55cm

Area of sector

Xπr 2/360

150x22x21x21/36x 7

=577.50 cm2
