Answer: d ≈ 5.73 ft

Step-by-step explanation: Using the formulas

                                             C=2πr

                                             d=2r

                                             Solving for d

                                             d= C/π = 18/π ≈ 5.72958ft

Answer:

5.732484076 =d

Step-by-step explanation:

The circumference is given by

C = pi*d

18 = 3.14 *d

Divide each side by 3.14

18/3.14 = 3.14d/3.14

5.732484076 =d

Answer:

                \dfrac{1}{30}

Step-by-step explanation:

6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:

6•5•4•3 = 360

If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.

So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:

1•1•4•3 = 12

The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:

\dfrac{1\cdot1\cdot4\cdot3}{6\cdot5\cdot4\cdot3}=\dfrac{1\cdot1}{6\cdot5}=\dfrac{1}{30}
