Question

the area A of a sector circle is given by A= ... idk how to write that so look at the image please lol

Answer 1

A=πr^2s/360  multiply both sides by 360

360A=sπr^2  divide both sides by πr^2

s=360A/(πr^2)

Answer 2

It's D
but the problem is wrong
at the end shoud have been
Solve the equation for S to find the angle measure given the radius and the area of the SECTOR not the circle
if they give you the radius of the circle then...
the area is redundant since circle area is pi*r^2
