Circumference=2 x pi x radius
diameter=13, so 13/2=6.5=radius

2 x 3.14 x 6.5=40.82m around.
 40.82/2.5(length of each piece)= 16.33 or 17 pieces needed.

vitfil [10]
To find the volume of a cylinder, you use this formula:
V = \pir^{2}h

Plug in your numbers,
V = (3.14 * 8^{2}) * 13

Exponents:
V = (3.14 * 64) * 13

Parentheses:
V = 200.96 * 13

you have a bag full of 17 marbles. Of those marbles, 3 are black. What is the probability that a marble chosen is not black
sdas [7]
Total number of marbles = 17

3 are black.

Not black = 17 - 3 = 14.

Probability of not black =          Number not black / Total

                                       =     14 / 17
