Answer:
a
Step-by-step explanation:
Answer: The answer is (c) ln 4768 = 5x.
Step-by-step explanation: The given equation is

We are to find the logarithmic form of the above equation.
We will be using the following properties of logarithm :

The solution is as follows:

Thus, the correct option is (c).
Solution:
<u>Note that:</u>
- Circumference = 50.24 ft = 2πr = πd
- Dia. = 16 ft.
<u>Divide the diameter both sides.</u>
- 50.24 ft = πd
- => 50.24/d ft = πd/d
- => 50.24/d ft = π
<u>Substitute the diameter in the equation.</u>
- => 50.24/16 = π (Option A)
