Answer:
10 m
Step-by-step explanation:
The circumference of a circle is given by
C = pi*d
Substituting what we know
30 = pi*d
Divide each side by pi
30/pi = d
Pi is approximately 3.14
30/3.14 = d
9.55 =d
The closest number is 10
Answer:
22.22%
Step-by-step explanation:
If it is exactly a red, it means that it is removed on the first or second attempt, but only once, in this case it does not matter if it is on the first or second attempt because the marble is returned to the bag.
So suppose that on the first attempt red is drawn, the probability would be:
4 / (3 + 4 + 5) = 4/12 = 1/3
Now, on the second attempt, it is not to draw a red, it must be green or blue, so it would be:
(5 + 3) / (3 + 4 + 5) = 8/12 = 2/3
The final probability then is:
1/3 * 2/3 = 0.2222
that is, the probability is 22.22%
