Use the shell method. The volume is
<em>V</em> = 2<em>π</em> ∫₅⁸ (<em>x</em> - 5) <em>x</em> ² d<em>x</em>
<em>V</em> = 2<em>π</em> ∫₅⁸ (<em>x</em> ³ - 5<em>x</em> ²) d<em>x</em>
<em>V</em> = 2<em>π</em> (1/4 <em>x</em> ⁴ - 5/3 <em>x</em> ³) |₅⁸
<em>V</em> = <em>π</em>/6 (3<em>x</em> ⁴ - 20<em>x</em> ³) |₅⁸
<em>V</em> = <em>π</em>/6 ((3 × 8⁴ - 20 × 8³) - (3 × 5⁴ - 20 × 5³))
<em>V</em> = 891<em>π</em>/2
Each side would be = square root of 64 which is 8m
Perimeter = 8 * 4 = 32 m.

The centroid is the intersection point <span>of the medians.
</span><span>So the distance from any vertex to the </span><span>centroid is 2/3 the length.
</span><span>BG=1/3*BE and GE=2/3*BE
</span><span>
So answer: </span>BG = 4, GE = 8
