Question

The radius of a circle is 21cm and the sector makes an angle 75degrees at the center.Then the area of the sector is​

Answer 1

Area of the sector is 0.0288 m ²

Step-by-step explanation:

area = (Ф / 360 ) π r*r

= (75/360) * 3.14 * .21*.21

= 0.0288 m ²

Answer 2

Answer:

Step-by-step explanation:

Given that a circle of radius 21 CM...

Theta of the sector = 75°

Therefore the formula for area of sector is equal to = theta/360 x π x r^2...

=> 75/360 x 22/7 x 21x21

=> 288.75...
