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!! :)

Answer:
53%
Step-by-step explanation:
Answer:
(a)25.45 million viewers
(b) 11.95 million viewers
Step-by-step explanation:
The average number of viewers from the 2011 season through the 2013 season is approximated by the function:
(1 ≤ t ≤ 4) where f(t) is measured in millions.
t = 1 corresponds to the 2011 season.
(a) In 2011, t=1
Average number of viewers in the 2011 season,
=25.45 million viewers
(b) In the 2014 season, when =4
=11.95 million viewers
assuming that the trend continued into that season
