When parentheses are around a number being squared, the output value will always be positive. 
For example: -2² vs (-2)²
-2² means the <em>negative of the square of two</em>, or -4
(-2)² means the <u /><em>square of negative two</em>, or 4
<em />
        
             
        
        
        
Answer:
x ≈ 34.88 square cm
Step-by-step explanation:
Solve by proportional formula:
Area of a sector/area of circle* = sector central arc measure/360
*area of a circle = πr²
x/(53.29π) = 75/360
x/53.29π = 0.2083
x = 11.1020833π
x = 34.8782233
x ≈ 34.88 square cm
