Answer 2

Answer:

r=x+5

Step-by-step explanation:

Area of circle=πx²+10πx+25π

                πr²=πx²+10πx+25π

                πr²=  π(x²+10x+25)

                  r²= (x²+10x+25)  

                  r²= (x²+2×5×x+25)                                                    a²+2ab+b²=(a+b)²

                  r²= (x+5)²  

                  r=x+5
