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 .
In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
I think the answer would be three because if you multiply all of the numbers together you get 30.
