The diameter of a circle is 13 cm. What is the radius of the circle?

nikklg [1K]

Answer:

The Radius is 6.5 cm.

Step-by-step explanation:

We know that the diameter of a circle is a line that begins on one point of a circle and ends on the opposite side. We also know that the radius is a point on the circle that starts from that point and ends at the center. Therefore, the radius would be half the diameter.

$13/2 = 6.5$

Hope this helped :D!

Jennifer is taking a four question multiple choice test. each question has four possible answers. if she guesses on all of the q

xxTIMURxx [149]

Probability of getting the correct answer in the first question is 1/4
probability of getting the correct answer in the second question is 1/4
probability of getting the correct answer in the second question is 1/4 the probability that he gets one question wrong is 3/4
which is 1/4*1/4*1/4*3/4=3/256
for the four questions because he may get the first answer correct and my be the second question wrong, or the the third wrong and the other correct or the first wrong and others correct we should take care of all this by
multiplying 3/256*4=12/256
=0.046875
in three decimal places we have 0.047
