Answer:

\frac{9}{55}

Step-by-step explanation:

A goblet contains 3 red balls, 2 green balls and 6 blue balls.

Total balls = 3 + 2 + 6 = 11 balls

we choose a ball and then another ball without putting the first one back.

The probability that the first ball will be red = P_{1} = \frac{3}{11}

Second event is done without replacing the first ball so total ball will be 10

The probability that the second ball will be blue = P_{2} = \frac{6}{10} = \frac{3}{5}

P = \frac{3}{11} × \frac{3}{5} = \frac{9}{55}

The probability that the first ball will be red and the second ball will be blue is \frac{9}{55}

Who can help with geometry
Kay [80]

Answer:

h = 21.5cm.

Step-by-step explanation:

<em>Step one:</em> Simplify the volume.

220.16 x (pi) = 691.65cm^3.

<em>Step two:</em> Isolate h.

Cylinder volume equation: V = (pi)(r^2)(h), where r is the radius and h is the height.

Divide out the pi and r^2 on both sides to isolate h and move the equation to V/(pi)(r^2) = h.

<em>Step three:</em> Solve for h.

691.65/(pi)(3.2^2) = 21.5cm rounded to the nearest tenths place.

To illustrate this, please check the diagram below.
