All the options are incorrect, if you're talking about circle! which is most common
C = 2πr..... It is the relation for Circle's if you're considering something else, then, please mention!
I think your answer is correct

0.75 is the answer to the question
Answer: a and b
Step-by-step explanation: plug in
Answer:
B
Step-by-step explanation:
Given a sinusoidal function in the form f(x) = A Sin (Bx + C), we can say that:
A is the amplitude (if A is negative, the Amplitude is still the positive)
Period is
To get phase shift, we set Bx + C = 0 and solve for x.
Now, the function given is f(t) = -5 Sin (7t -1)
Hence, amplitude is 5
period is
and, phase shift is:
7t - 1 = 0
7t = 1
t = 1/7
Answer choice B is right.
