Volume Formula [Cone]:
<em>r</em> is radius <em>h</em> is height Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given</em>.
<em>h</em> = 8 ft
<em>C</em> = 23.236 ft
<u>Step 2: Find Radius </u><u><em>r</em></u>
[Circumference Formula] Substitute in variables: Solve [Equality Properties]:
<u>Step 3: Find Volume</u>
[Volume Formula - Cone] Substitute in variables: Evaluate: ∴ the <em>volume </em>of the artist-created sculpture is 114.631 ft³ .

<h3>Answer: Radius</h3>
Let point A be the center of the circle. Point B is somewhere on the circle edge. The distance from A to B is equal to the radius. The radius is half the diameter which spans the whole circle and it goes through the center. The circumference is the curved distance around the whole circle's perimeter.
Yards because inches are too small walls are normally really long and wide and using inches wouldn't be wise in this case.
