Acircular piece of glass has a radius of 1.2 meters. the glass sells for $7.10 per square meter. what is the total cost of the circular piece of glass?

To do this, take the 7.10 and add it to 20% of the 7.10 which equals 1.42 to get an expression of 7.10 + 1.42 = $8.52.

Hope that this helped! If it did, please give me a good rating and mark me brainliest for my hard work. Thanks!
