Question

the angle of a sector is 90 degrees and it's radius is 28cm then the area of sector in square centimeters is

Answer 1

Area of sector = thita / 360 * pi * r *r
90/360 * 22/7 * 28 * 28
22 * 28
= 616 cm square

Answer 2

Heya..


This is your answer.

Given :-  
theta = 90 degree.
radius = 28 cm.

By using formula.
$area of sector = \frac{theta}{360} X pi X r^{2} \\ = \frac{90}{360} X \frac{22}{7} X28X28 \\ = 22X28 \\ =616 cm^{2}$

Hence, the area of sector is 616 cm².

Hope it helpsss
