A diagram of a stained-glass window.

Answer 1

I don’t see the diagram, so I need one detail: is the window a rectangle with the two quarter-circles cut out of the top corners (concave), or are the quarter-circles added on (convex)? Also tell me the overall rectangle dimensions (width and height) or upload the picture.

How to solve (once you give the missing dimension):
- Area of one quarter circle of radius 4 = (1/4)π(4^2) = 4π.
- Two quarter circles = 8π. Using π = 3.14, that equals 8 × 3.14 = 25.12 in^2.
- If the quarter-circles are cut out of a rectangle of width W and height H, window area = W·H − 25.12.
- If the quarter-circles are added onto a rectangle, window area = W·H + 25.12.

Give the rectangle’s width and height or upload the diagram and I’ll compute the numeric answer.
