A circular piece of glass has a radius of 0.8 meters. The glass sells for $4.60 per square meter. The total cost of the circular piece of glass is $9.24.
Area of a circle is pi*r^2 = 3.14*0.8^2 = 2.0096 square meter.
2.0096 * $4.60 = $9.24

Okay, that makes sense. But if the question is asked the way it is in this conversation, What are the square roots (plural) then tektek10's answer is correct.
