The cost to replace the glass is $520.96
Step-by-step explanation:
- Step 1: Find area of the window. It can be found by finding the areas of the 2 semi circles and the rectangle.
Area of the rectangle = length × width
Here, length = 5 ft and width = 4 ft
∴ Area = 5 × 4 = 20 ft²
Area of 2 semicircles = 2 × 1/2 × πr² = πr²
Here, radius of both the semicircles = 2 ft
∴ Area = π × 2² = 3.14 × 4 = 12.56 ft²
⇒ Area of the window = 20 + 12.56 = 32.56 ft²
- Step 2: Find the cost of glass to replace the window.
Cost of glass per sq. foot = $16
⇒ Cost of 32.56 sq. ft = 32.56 × 16 = $520.96
