A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.
Area of a circle: A = pi x r^2
r = 40 / 2 = 20
A = pi x 20^2
A = 400pi / 2 = 200pi
200pi = 628.32
The area of the lunette is approximately 628 in^2.
Hope this helps!! :)
