Answer: $1226.55
Step-by-step explanation:
Calculate the area of the circle.
[tex]A=\pi r^2[/tex]
You do not have the radius, but you do have the diameter. Divide the diameter by 2 in order to find the radius.
[tex]\frac{d}{2} =\frac{25}{2}=12.5m[/tex]
Plug into the formula:
[tex]A=(3.14)(12.5m)^2\\A=(3.14)(156.25m^2)\\A=490.62m^2[/tex]
Now, each square meter costs $2.50, calculate how much it costs to cover 490.62 square meters.
[tex](2.50)(490.62)=1226.55[/tex]
