Below is the formula for the circumference of a circle
C = 2πr
This question gives us the diameter. To find the radius (r) you would divide the diameter by two like so...
16.4/ 2 = 8.2
Plug what you know into the formula and solve...
π = 3.14
r = 8.2
C = 2(3.14)(8.2)
C = 6.28(8.2)
C = 51.496
In the question it asks to round to the nearest tenth like so...
51.5
Hope this helped!

The logarithmic function when the temperature is 64 degrees is given as
ln f(x) = x ln 2.

What is a logarithmic function?</h3>
A logarithmic function is the inverse of an exponential function. It is to be noted that all exponential functions can be written as logarithmic functions.
Hence, to convert the mathematical statement above into a logarithmic function we say:
f(x) = 2ˣ
ln f(x) = ln 2ˣ
ln f(x) = x ln 2
Ln 64 = x Ln 2
Let f(x) = 64;
Hence,
Ln 64 = x ln 2
Divide both sides by ln 2 to get x
ln 64/ln 2 = x
Hence,
x = ln 64/ln 2
= 6
