step 1 :
Because soccer ball is in the shape of sphere, we can use the formula of volume of a sphere to find volume of the soccer ball.
Write the formula to find volume of a sphere.
V = <span>4/3 · ∏r</span>³ ----- (1)
Step 2 :
To find the volume, we need the radius of the sphere. But, the diameter is given, that is 24 cm. So, find the radius.
r = diameter / 2
r = 24/2
r = 12
Step 3 :
Plug ∏ ≈ 3.14 and r = 12 in (1).
<span>V ≈ 4/3 </span>· 3.14 · 12³
Simplify.
<span>V ≈ 4/3 </span>· 3.14 · 1728
<span>V ≈ 7,234.6</span>
<span>Hence, the volume of the soccer ball is about 7,234.6 cubic cm. </span>

Step-by-step explanation:
If you would like to know how many pounds of each kind of candy must the grocer use to make 100 pounds worth 85 cents a pound, you can calculate this using the following steps:
Candy number 1:
c pounds = ? ... 90 cents a pound
Candy number 2:
d pounds = ? ... 40 cents a pound
c + d = 100 pounds
c = 100 pounds - d
c * 90 cents + d * 40 cents = 100 pounds * 85 cents
(100 - d) * 90 + d * 40 = 100 * 85
100 * 90 - 90 * d + d * 40 = 100 * 85
100 * 90 - 100 * 85 = 90 * d - 40 * d
500 = 50 * d
d = 500 / 50
d = 10 pounds
c = 100 pounds - d = 100 - 10 = 90 pounds
There should be 90 pounds of candy number 1 and 10 pounds of candy number 2.
90 pounds * 90 cents + 10 pounds * 40 cents = 8500 cents per 100 pounds
8500 cents / 100 pounds = 85 cents a pound
0.222 is 222/1000, which reduces to 111/500.
Two tenths, or 2/10 is equal to 0.2. It is also equal to 1/5.
Now, let x = 0.22222222.....
let 10x = 2.22222.........
Then, 9x = 2.000.... i.e., 9x = 2, or x = 2/9.
So, 2/9 = 0.222222222......
The literal answer to your question is:
Answer:
0.222 = 111/500
