A vase contains 4 pink roses, 8 red roses, and 10 white roses. Two roses are randomly selected from the vase one at a time, with

alisha [4.7K]

There are 22 roses in the vase
probability of first selecting a red rose = 8/22 = 4/11

P( second one is red) = 7/21 = 1/3

these probabilities are multiplied because the individual picks are independent
so the answer is 4/11 * 1/4 = 4/33

Find the volume of the sphere with a diameter of 22 and round to the nearest 10

maksim [4K]

Answer:

$\huge\boxed{\sf Volume = 16728.8 \ units^3}$

Step-by-step explanation:

Diameter = 22 units

Radius = 11 units

$\rule[225]{225}{2}$

$\sf Volume = \frac{4}{3} \pi r^3\\\\Volume = \frac{4}{3} (3.14)(11)^3\\\\Volume = \frac{4}{3} (3.14)(1331)\\\\Volume = \frac{4}{3} (4184.5)\\\\\bold{Volume = 16728.8 \ units^3}$
