Step-by-step explanation:

\frac{5}{6}  +  \frac{2}{3}

\frac{5}{6}  +  \frac{2 \times 2}{3 \times 2}

\frac{5}{6}  +  \frac{4}{6}

=  \frac{5 + 4}{6}

=  \frac{9}{6}

=  \frac{3}{2}

= 1 \frac{1}{2}

The vertical cross-section of a solid is shown below has 10 in every side angle
Vlad1618 [11]
I think I know what it forms - a cone!!

I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB = <span> <span> <span> 68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume = <span> <span> <span> 29,551
That is just the "upper cone volume.  So, we multiply </span></span></span><span><span> <span> <span> 29,551 * 2
and get 59,102 which is the volume of the entire solid.

a² - b² = (a - b)(a + b) , then

x² - 5

= x² - (\sqrt{5} )²

= (x - \sqrt{5} )(x + \sqrt{5} )
