The correct answer is k=6.03968419. Hope this helps! ;D
Answer:
A = 9 pi cm^2
Step-by-step explanation:
Circumference = 2 * pi *r
6pi = 2 * pi *r
Divide each side by pi
6 = 2r
Divide by 2
6/2 = 2r/2
3=r
Now we want to find the area
A = pi r^2
A = pi (3)^2
A = 9 pi cm^2

<span>Let x = third side
Using the Triangle Inequality theorem which states that the sum of two sides of a triangle must be longer than the third side and the difference of the two sides is the lower limit of the third side, the answer to your question is that the third side must be between 3 and 13, or written using inequalities, 3 < third side (or x) < 13 is the range.</span>
