Question

Solve for a.

c = \pi a b

Answers?
1) c/8 = a
2) c/8\pi = a
3) 8 \pi b c = a
4) c / 8\pi b = a

Answer 1

The answer is D I just took the test.

Answer 2

I believe the correct answer from the choices listed above is option 3. To solve for a, we need to transfer all terms and variables to one side and isolate the variable a. We do as follows:

c = 8/pi a b

(c = 8/pi a b)a/c

8 /pi b c = a
