A circular piece of fabric has a radius of 1.2ft. The fabric sells for $5.40 per ft2. What is the total cost of the circular piece of fabric

Find the area of the fabric

The fabric is circular, so we find the area using the area of circle formula

a = π * r²

input the numbers

a = π * r²

a = 3.14 * (1.2) ²

a = 3.14 * 1.44

a = 4.5216 ft²

Calculate the total cost

Multiply the cost by the area

cost = 5.4 * 4.5216

cost = 24.417

The total cost is approximately $24.42
