Answer:

111 in

Step-by-step explanation:

Let the remainder of the diameter is x.

<u>Use the intersecting chords theorem:</u>

6*x = (72/2)*(72/2)
6x = 1296
x = 216

<u>The diameter:</u>

d = 6 + x = 6 + 216 = 222 in

<u>The radius:</u>

r = 222/2 = 111 in

How do i solve for x by using natural log (in)?

Helga [31]

Unfortunately you cannot use logs to solve this.

However, it shouldn't take too long to use guess-and-check to see that

$2^x+3^x = 2^2+3^2 = 4+9 = 13$

Showing that x = 2 is the solution to the equation.

You can use a graphing calculator to graph out $y = 2^x+3^x$ and $y = 13$ . The two curves cross at (2,13). The x coordinate of that intersection is what we're after. GeoGebra and Desmos are two free options you can pick from in terms of a graphing calculator.
