(9×6/2) × 12 = 324
Explination:
The easiest way to understand what you're doing is to find the area of the base first, then extend it upwards to find the volume using height. Hence the equation: b×h=v
So how do we find the base of a triange? Remember that every single triangle can be calculated as a square, then cut in half. So 9 × 6 / 2 = 27 cm2
The next step is to calculate the volume using the height of the figure. 27 × 12 = 324 cm3
**<em>remember to </em><em>use</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>units</em><em>,</em><em> </em><em>since</em><em> </em><em>area</em><em> </em><em>and</em><em> </em><em>volume</em><em> </em><em>are</em><em> </em><em>different</em><em>. </em>

The first thing we must do for this case is to find the diameter of the circle.
We have then:
d = 2 * r
Where,
r: radius
Substituting:
d = 2 * (3.25)
d = 6.5 feet
We now look for the perimeter of the square.
P = 4L
Where,
L: square side
L = d = 6.5 feet ("a circular spa that will be enclosed by a square deck")
Substituting we have:
P = 4 * (6.5)
P = 26 feet
Answer:
The perimeter of the deck, in feet is:
P = 26 feet
Stem and leaf plot is the correct answer!!
