We just did one like this; let's do this a different way.

V=\frac 1 3 \pi r^2 h

2 \pi r = 9.8 \textrm{ in}}

r = 9.8 / (2 \pi) \approx 1.55972

V=\frac 1 3 \pi r^2 h = (1/3) \pi (1.55972)^2(6.7) = 17.01

Answer: 17.1 cubic inches

Solve for x using the given diagram
blagie [28]

Answer:

<h2>x = 1</h2>

Step-by-step explanation:

Look a t the picture.

The triangles on the picture are similar.

Therefore the sides are in proportion:

\dfrac{8x}{10}=\dfrac{4}{5x}              <em>cross multiply</em>

(8x)(5x)=(4)(10)

40x^2=40           <em>divide both sides by 40</em>

x^2=1\to x=\sqrt1\\\\x=1
