Area of a circular play parachute:
A = 324 ft²
A = r² π
r² π = 324
r² = 324 : 3.14
r² = 103.1874
r = √103.1874
r = 10.157987 ≈ 10.2 ft
If point

is on the unit ircle, then:

Since, the point is in the second quadrant, x is negative.
Thus,

Part A:

Therefore,

.
Part B:

Therefore,
Remember that a dilation stretches or compresses an object based on a given scale factor, therefore, the correct option is C
I think it’s 90 just add them up the subtract 180
