Question 310892: A circular window of radius 12 inches is to be laminated with a sunblock coating that costs $0.65 per square inch to apply. What is the total cost of coating the window, to the nearest cent? (Use п = 3.14. Hint: Area of Circle: A = пr2)

You can put this solution on YOUR website!
Find the area of the window.
Multiply by the cost/area of coating to get the total cost.
C=0.65%2A%28pi%2AR%5E2%29=0.65%2A%283.14%2A12%5E2%29=293.90
It would cost $293.90 to coat this window.
