We have to calculate the pizza´s area.
r=radius
Area (circle)=π*r²
diameter=30 cm
radius=diameter/2=30 cm/2=15 cm
Area(pizza)=π*(15 cm)²=225π cm²≈706.86 cm².
solution: 706.86 cm²

Answer:
-3
Step-by-step explanation:
Subtract 25x             125=-25x+50
Subtract 50                125-50= -25x
Simplify                       75= -25x
Divided 75 by negatrive 25
 
        
             
        
        
        
4(x + 9) + 5x = 9x - 36 
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true. 
So there is no solution for this equation.
Answer is C. no real solutions
