The formula to find the circumference of a circle is 2 x pi (π) x radius. The radius is half of the diameter. Therefore, since the diameter is 20, the radius is 10. Pi is equal to approximately 3.14.
3.14 x 10 x 2 is 62.8.
The circumference of the circle is 62.8 m.

Answer:
The probability that both are red is 
.
Step-by-step explanation:
Probability is simply how likely something is to happen and its given by
<em>Probability of an event = (# of ways it can happen) / (total number of outcomes)</em>
Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs.
At our first pull, there is an 
chance that a red will be pulled.
At the second pull there is a 
chance that the second marble will be red.
Therefore, the probability that both are red is
Answer:
D) 90%
Step-by-step explanation:
We have the percentages of students who go to public schools (84%), those who go to college (23%) and those who go to public college (17%).
We know that if you go to the public college, you go to the college, which means that it is a reduction with respect to the question, which is the percentage that goes to public schools and to the college (either public or private). This means that the percentage of public colleges must be subtracted from college because they are already included.
Therefore, the answer would be:
84% + 23% - 17% = 90%
90% of US students attend either public school or college, so the answer is D)
Simplified version would be 3 square root of 11
