Question

The area of a sector of a circle is given by the equation A=3.14r^2S/360, where r us the radius of the circle and S is the angle measure of the sector. If Mia solved this equation for S, which of the following equations did she write?

Answer 1

Just took the quiz.

The answer is 360A / pi r^2

Answer 2

A=3.14r²s/360
to solve for s we proceed as follows:
multiply both sides by 360, this will give us:
360A=3.14r²S
next we divide both sides by 3.14r²
360A/(3.14r²)=(3.14r²S)/(3.14r²)
This will give us:
S=360A/(3.14r²)
