Answer is A or your first option.
A=πr^2s/360 multiply both sides by 360
360A=sπr^2 divide both sides by πr^2
s=360A/(πr^2)
Answer: C
Step-by-step explanation:
On the left side, there are 2 triangles and 6 2's, so this equals 2x+12.
On the right side, there are 4 triangles and 2 2's, so this equals 4x+4.
Meaning 2x+12=4x+4.
12=2x+4
2x=8.
