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

Area of a circle is pi*r^2 = 3.14*0.8^2 = 2.0096 square meter.

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.

Added 4/20/2014 11:30:09 PM

I agree with Deb. The question was asked clearly. I got the same answer as tektek's.
