Direct answer:
The volume of the sphere having diameter 21.6 cm is 5278.79 cm³.
The volume of the sphere having diameter 16 cm is 2145.52 cm³.
The volume of the sphere having diameter 24 cm is 7241.14 cm³.
The volume of the sphere having diameter 6 cm is 113.14 cm³.
Explanation:
Given diameter = 21.6 cm
So radius = diameter/2 = 21.6 cm /2 = 10.8cm
Now volume of the sphere is given as = 4/3 πr³
So Volume = 4/3 × 22/7 × (10.8)³
Volume = 5278.79 cm³
Similarly given diameter = 16 cm,
So radius= 16/2 = 8 cm
Hence volume = 4/3× 22/7 × (8) ³
Volume = 2145.52cm³.
Similarly given diameter = 24 cm
So radius = 24/2= 12 cm
Hence volume= 4/3 × 22/7× (12) ³
Volume = 7241.14 cm ³
Similarly given diameter = 6 cm
So radius = 6/2= 3 cm
Hence volume= 4/3 × 22/7× (3) ³
Volume = 113.4 cm ³

Detailed Answers:

Volume of a Sphere (V) = 4/3 πr^3

1. Diameter (d) = 21.6 cm
Radius (r) = 21.6/2 = 10.8 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (10.8)^3
= 4/3 * 22/7 * 1259.712
= 88/21 * 1259.712
=> 5278.79

Volume (V) = 5278.79 cm^3

2. Diameter (d) = 16 cm
Radius (r) = 16/2 = 8 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (8)^3
= 4/3 * 22/7 * 512
= 88/21 * 512
=> 2145.52

Volume (V) = 2145.52 cm^3

3. Diameter (d) = 24 cm
Radius (r) = 24/2 = 12 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (12)^3
= 4/3 * 22/7 * 1728
= 88/21 * 1728
=> 7241.14

Volume (V) = 7241.14 cm^3

4. Diameter (d) = 6 cm
Radius (r) = 6/2 = 3 cm

Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (3)^3
= 4/3 * 22/7 * 27
= 88/21 * 27
=> 113.14

Volume (V) = 113.14 cm^3

kati45 [8]

Question:

Morgan is playing a board game that requires three standard dice to be thrown at one time. Each die has six sides, with one of the numbers 1 through 6 on each side. She has one throw of the dice left, and she needs a 17 to win the game. What is the probability that Morgan wins the game (order matters)?

Answer:

1/72

Step-by-step explanation:

<em>Morgan can roll a 17 in 3 different ways. The first way is if the first die comes up 5, the second die comes up 6, and the third die comes up 6. The second way is if the first die comes up 6, the second die comes up 5, and the third die comes up 6. The third way is if the first die comes up 6, the second die comes up 6, and the third die comes up 5. For each way, the probability of it occurring is  1/6 x 1/6 x 1/6 = 1/216. Therefore, since there are 3 different ways to roll a 17, the probability that Morgan rolls a 17 and wins the game is  1/216 + 1/216 + 1/216 = 3/216 = 1/72</em>
