A = pi (y+5)²/4 = (pi/4) (y² + 10y + 25)

]]>(BTW: you can use the symbols at top. × ½ √ ∞ etc, just drag your mouse over one and copy and paste so you end up with A = π (d/2)² )

]]>So, you need the diameter of the circle, but I have no idea what the (y+5) is supposed to represent.

Can you elaborate?

P.S.

That's an algebra II problem? Huh?

The formula for the area A of a circle with diameter d is A=pi(d/2)squared. Write an expression to represent the area of the circle.

Also there is image of a circle to the right, i'm not sure if it's significant in any way, it shows circle, diameter line, dot in middle, and (y+5) over dot.

Can somebody please explain in detail how i understand/do these?
