I might be wrong but wouldn't it be ab/360 (pi r^2) - 1/2 bh?
I am not positive.
Answer:
352
Step-by-step explanation:
512 - 256 + 128 - 64 + 32 = 352
F(x) = 5*x - 12
f(2) = 5*2 - 12 .... replace every x with 2, then use PEMDAS to simplify
f(2) = 10 - 12
f(2) = -2
The final answer is -2, which is choice C
