Volume = 1/3 pi r^2 h
= 1/3 * 10^2 *81 pi
= 2700 pi units^3
Its C
Answer:
The equivalent equation is 
Step-by-step explanation:
p is given by the following relation:
And we are given the following equation:
On the right side, we can simplify. So
Replacing 
by p, the equation is:
Answer:
81
Step-by-step explanation:
Order of operations rules require that we do the work inside parentheses first. Multiplication must be done before addition. Thus, the quantity inside parentheses becomes 15 + 4 = 19.
Next, we evaluate 100 - [19], obtaining 81 (answer)
Using the concept of number line, the solution to the questions posed are :
- <em>Pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>height</em><em> </em><em>of</em><em> </em><em>slide</em><em> </em><em>is</em><em> </em><em>12</em><em> </em><em>meters</em><em> </em><em>above</em><em> </em><em>the</em><em> </em><em>pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>level</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>bottom</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>pole</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>marked</em><em> </em><em>as</em><em> </em><em>-</em><em>3</em>
The pool surface would be treated as sea level surface, such that, position below are marked as negative and position above are marked as positive.
- Therefore, the surface of the pool is <em>marked</em><em> </em>as the sea level position, 0.
- Since the slide is above the surface of the pool, it's value will the positive. Hence, the height of the slide is 12 feets.
- The marked position is below the <em>pool</em><em> </em><em>surface</em><em>,</em><em> </em>hence, it will take up a negative value of - 3 feets.
