no

ganeshie8 · Answer

Okay.

to find sector area :
1) find the area of circle
2) multiply the area with $\frac{\theta}{360}$

$\theta \textbf{ is the angle formed by sector}$

thats how you find the sector area?

ganeshie8 · Answer

yh

A full circle makes 360 degrees :  Area = $\pi r^2$
A sector makes $\theta$ degrees : Area = $\frac{\theta}{360} . \pi r^2$

ganeshie8 · Answer

if the sector forms 180 degrees (half circle), then $\theta = 180$ 
can you tell what area of sector will be

anonymous · Answer

okay, so you find the area of the circle , and then times it with $$\theta/360$$

yup and that makes sense right ? can you answer the question i asked as well... im not sure whether u get it or not thats why lol
