A semi-circular transom above a door is to contain a stained glass window. If the stained glass window costs $1.40 per square inch, how much will the window cost?

Lacking adequate data.

1.4 * (Pi * radius^2) / 2

To calculate the cost of the stained glass window, we need to find the area of the semi-circular transom.

The formula to find the area of a circle is A = π * r^2, where A represents the area and r represents the radius. However, in this case, we have a semi-circle (half of a circle), so we divide the formula by 2.

To calculate the radius of the semi-circular transom, we need more information. If you have the diameter of the transom, divide it by 2 to get the radius.
