1) we calculate the area of the circular piece of metal.
area=πr²
area=π(3.5 m)²=12.25π m² ≈ 38.48 m²
2)we calculate the total cost of the circular piece of meta by the rule of three.
$3.25-------------------1 m²
x--------------------------38.48 m²
x=($3.25 * 38.48m²) / 1 m²=125.06$
Answer: 125.06$
We can also calcultate the total cost of the ciucular piece of metal by the ratius.
Ratius=$3.25/1m²
Total cost=ratius * area of the circular piece of metal.
total cost=($3.25/ m²)*(38.48 m²)=$125.06
Answer: $125.06
