Replacement glass for energy-efficient windows costs $5.00 per square foot. About how much will you pay for replacement glass for a regular hexagonal window with a radius of 2 feet? A.$10.39
B.$27.78
C.$45.98
D.$51.96

Cost = $51.96

Step-by-step explanation:

The radius of a regular hexagonal window, r = 2 feet

The area of a hexagonal shaped figure is given by :

Put r = 2 feet in above formula

Replacement glass for energy-efficient windows costs $5.00 per square foot. It means, the total cost will be :

So, the required cost will be $51.96. Hence, the correct option is (d).
