Answer: 4.51 cm

Step-by-step explanation:o Area of circle=pi×r^2

Given area=64 cm sq.

so, 64=3.14×r^2

64/3.14= r^2

20.38= r^2

√20.38=r

4.51=r

Therefore, radius= 4.51 cm

There is a bag filled with 4 blue, 3 red and 5 green marbles.
zhannawk [14.2K]

Answer:

You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.

The probability of selecting a red marble the first time is 1313.

(This is because 4 out of 12 marbles are red and412412 reduces to 1313.

The probability of selecting a red marble the second time is 1313.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds = (13)2(13)2

=19=19.

So the probability of getting two reds is 1919.
