So what you are looking for is the hypotenuse of the triangle DCF.
We know DC is 3cm, so we need CF.
BC and CF and CF create a right triangle.
Using Pythagorean Theorem, CF is about 10.2
Now using Pythagorean Theorem again, 3^2 +10.2^2=113
The sqaureroot of that is 10.6. So 10.6 is your answer

Answer:
x=7.31
Step-by-step explanation:
There are two x's, so they represent the equation 2x=14.62. If we solve for x, we have to divide each side by 2:
2x/2=14.62/2.
If we divide, we get x=7.31
Answer:
The answer is 2pi.
