Given radius of circle = 0.8 meters

Area of circle = pi * r*r

Area =3.14 * 0.8 *0.8 = 2.0096 meter square

Cost of one square meter of glass = $4.60

cost of 2.0096 square meter of glass = 4.60*2.0096 = 9.24416

Cost of glass = $9.24416

Here given that r= 0.8

Area of circular glass = area of circle = pi r^2

= 3.14 ( 0.8)^2 = 2.009 square meter

cost of one square meter = 4.60

cost of 2.009 square meter = 4.60 * 2.009 = 9.244

Answer $ 9.244 .
