Answer:
The total cost is 28.26.
Step-by-step explanation:
The radius of the birdbath is 1.25 feet.
The cost per foot is 3.6 .
The formula for perimeter of circle is given by,
= 2πR , where R is the radius of circle.
Inserting the above value of radius in the equation above,
circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 [tex]ft^{2}[/tex]
Thus the total cost is,
= (7.85)(3.6) = 28.26
