Question

the angle of a sector is 90 degrees and its radius is 28 CM then the area of sector is in square cm is 666 , 616 , 717 , 720

Answer 1

Hi Sister!!!

This is your answer.

Given.
Angle of sector, theta = 90°
Radius of sector, r = 28 cm.

We have to find the area....

$area \: of \: sector \: = \frac{theta}{360} \times \pi \times {r}^{2} \\ = \frac{90}{360} \times \frac{22}{7} \times 28 \times 28 \\ = 22 \times 28 \\ = 616$
Hence, the area of sector is 616 cm².

hour you got the answer
