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!! :)

b. True. irrational numbers are closed under the sum operation, therefore, the sum of two irrationals numbers is always a irrational number.
c. True. The square of a real number is always a number greater than zero, and the sum of two numbers greater than zero is greater than zero.
d. True. The real numbers are closed under the product operation, then if a and b are reals numbers, the product ab is also a real number.
