Answer:
-11
Step-by-step explanation:
Average rate of change =
Where,
a = 3, f(a) = 33
b = 6, f(b) = 0
Plug in the values into the formula
Average rate of change =
Average rate of change = -11
The answer would be found by multiplying 9 or the radius sqaured by 3.14 or pi... giving you the answer 28.27 units squared.
Sec θ = 3
1/cos θ = 3
1/sin(90 - θ) = 3
csc(90 - θ) = 3
