What is the exact volume of the cone

Travka [436]

Answer:

V = $\frac{400}{3}$ $\pi$

Step-by-step explanation:

Volume of a cone is:

$V = \pi r^{2} \frac{h}{3}$

Substitute values given:

$V = \pi (5^{2} )(\frac{16}{3})$

$V = \pi (25)(\frac{16}{3} )$

V = $\pi \frac{400}{3}$

V = $\frac{400}{3}$ $\pi$

Can someone answer this pls??

<h3><u>Explanation</u></h3>

Given the expressions and values.

$\frac{2ab + {a}^{2} {b}^{2} - a}{ab} \\ \begin{cases} a = - 1 \\ b = 1 \end{cases}$

Substitute the value of a and b in the expression to evaluate.

$\frac{2( - 1)(1) + {( - 1)}^{2} {(1)}^{2} - ( - 1)}{( - 1)(1)}$

Evaluate

$\frac{2( - 1) + 1(1) + 1}{ - 1} \\ \frac{ - 2 + 1 + 1}{ - 1} \\ \frac{ - 2 + 2}{ - 1} \\ \frac{0}{ - 1} \Longrightarrow 0$
