The answer is a that should be it !
It’s A because look at the the triangles
with that template in mind, let's check,
notice, g(x) has a horizontal shift of C/B or +0/2, or just 0, none.
while f(x) has a horizontal shift of C/B or -4/2, or -2, to the right.
so f(x) is really just g(x), but shifted horizontally over 2 units to the right.
The formula for area of a circle is (pi)*radius^2
Radius is half of diameter so the radius is 2.
2 squared is 4, then multiply by pi to get an answer of 4(pi) or 12.56.
Answer:
A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.
(this may be more of an architect's job, as they are the ones that design the houses)
or
An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
