Question

The formula for finding the area of a sector of a circle is A=πr^2(x/360) , where r is the radius of the circle and x is the measure of the central angle of the sector.
Solve for x.
 

x=360πr2A
x=360Aπr2
x=A360πr2
x=Aπr2360

Answer 1

A = π r² $(\frac{x}{360})$

360A = π r² x

$\frac{360A}{\pi r^{2} } = x$

Answer: B
