Since point M is the midpoint of LN, LM and MN are equivalent in length.

7x - 12 = 3x + 16 (LM=MN)

7x = 3x + 28

4x = 28

x = 7

Now that we know the value of x, we can find the value of LM by plugging the value in the equation.

LM = 7(7) - 12

LM = 49 - 12

LM = 37

Answer:

The answer is "19 inches and 60 inches".

Step-by-step explanation:

Throughout this question, the choices were missing that's why its correct solution can be defined as follows:

The formula for diameter= $d=2r$

The formula for circumference = $C=2\pi r$

let the r=9.5 so, the diameter and the circumference are:

$\to d= 2 r= 2\times 9.5 =19\\\\\to C= 2 \pi r= 2\times \frac{22}{7} \times 9.5 =59.71 \approx 60 \\\\$
