Step 1. Calculate the area of the <span>circular piece of fabric. Step 2. Multiply the area of the piece by the price of </span><span>$5.40 per ft² to get the total cost.
Step 1. The area (A) of the circle with radius r is: A = </span>π r² π = 3.14 r = 1.2 ft
A = 3.14 * (1.2 ft)² A = 3.14 * 1.44 ft² A = 4.52 ft²
Step 2. Make a proportion 1 ft² costs $5.40 4.52 ft² cost x
1 ft² : $5.40 = 4.52 ft² : x x = 4.52 ft² * $5.40 / 1 ft² x = $24.41
