Find volume of cone z=sqrt(x^2+y^2) that is bounded with z=5 and z=7
Nina [5.8K]
Convert to cylindrical coordinates first, using

\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}

Then the volume is

\displaystyle\int_{\zeta=5}^{\zeta=7}\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=\zeta}r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta
=\displaystyle\pi\int_{\zeta=5}^{\zeta=7}\zeta^2\,\mathrm d\zeta
=\dfrac{218\pi}3

The expression 2x(5x - 1) +(3x2 - 7x - 2) is simplified into the form ax 2+ bx + c.
Yanka [14]

Step-by-step explanation:

2x (5x - 1) + (3x^2 - 7x - 2)

= 10x^2 - 2x + 3x^2 - 7x - 2

= 13x^2 - 9x - 2

a = 13

b = -9

c = 2
