Answer:
A
Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A =
πr²
We see that the radius is half of the diameter or r = 6 in.
A =
(3.14)(6)²
A = 56.52 in²

Step-by-step explanation:
Answer:
Coterminal angles are angles with the same terminal side.
When we have an angle A, the coterminal angles can be written as:
A + k*(360°)
where k can be any integer number. (Notice that when we have k = 0, means that A is coterminal with itself)
Then the set of all the coterminal angles to -225° is:
{-225° + k*360°I k ∈ Z}
where Z is the set of integer numbers.
