To find a 2-dimensional shape like a cylinder you say V=πr²h
to find a 3-dimensional shape like a sphere you will have V=4πr³÷3
Answer: 9 1/3 - 2/3 = 8 2/3 .
___________________________________
Note: If the answer were "8 1/3" ;
then: "8 1/3 + 2/3 =? 9 1/3 ? "
→ "8 1/3 + 2/3 = 8 3/3 = 8 + 1 = 9 = only "9" ;
____________________________________________
So the answer has to be MORE than "8 1/3"
Try "8 2/3" → "8 2/3 + 2/3 =? 9 1/3?" ?? ;
→ "8 2/3 + 2/3 = 8 4/3 = 8 + 1 1/3 = 9 1/3 " → Yes!
_________________________________________________
So, the answer is: "8 2/3" .

Another method:

Given the problem: "<span>9 1/3 - 2/3 " ;
___________________________________
Note that: "2/3 = 1/3 + 1/3"
__________________________________
So, "</span><span>9 1/3 - 2/3 = 9 1/3 - (1/3 + 1/3) = 9 1/3 - 1/3 - 1/3 = ?
________________________________________________
Start with: "</span>9 1/3 - 2/3" = 9. Then 9 - 1/3 = 8 3/3 - 1/3 = 8 2/3.
<span>______________________________________________________
</span>Another method:
____________________________
Given the problem:
____________________________
"9 1/3 - 2/3 = ?? " ;
____________________________
Convert "9 1/3" into "28/3" ; ("3*9 = 27"); ("27+1=28");
(The "3" comes from the "3" in the: "1/3" portion.)
_________________________________________________________
So, we rewrite as:
_____________________________________
28/3 - 2/3 = (28 - 2) / 3 = 26/3 ; or, 8 2/3 .

Answer:
Volume of the cylinder is. 1017.36
Step-by-step explanation:
is the area of a cylinder.
Let's plug in our values.
-----
3.14 = pi
9 = radius
x = height
-----
V = (3.14)(9)^2(4)
V = (3.14)(81)(4)
V = (3.14)(324)
V = 1017.36
The initial cost is 189.69. It is marked up 30%.
By simple calculations,
Final cost of the tablet computer = Initial price + 30% of marked price
= 189.69 + (30/100 x 189.69)
This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7
