Identify the volume of a cone with radius 6 m and height 11 m. HELP PLEASE!!

Lera25 [3.4K]

Answer: 414.48

Step-by-step explanation:

r: the radius of the base

h: height

The volume of a cone is given by:

V = π ∙ r2 ∙ h / 3,

where π ∙ r2 is the base area of the cone.

π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.

What is the value of the discriminant for the quadratic equation zero equals 2x^2+x-3

Liono4ka [1.6K]

Discriminant for the quadratic equation $2x^2+x-3=0$ is $d=25$

How to find the d Discriminant of the quadratic equation ?

We know that the standard quadratic equation

$ax^2+bx+c=0$

Discriminant of the equation is $d=b^2-4ac$

Equation given in the question is

$2x^2+x-3=0$

So we can find the values of $a,b,c$

$a=2\\b=1\\c=-3$

Substitute the values

$d=1^2-4*2*(-3)\\d=1+24\\d=25$

$\implies {\blue {\boxed {\boxed {\purple {\sf { \: A. \:- 8 {v}^{4} + 3 {v}^{3} + v + 5}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$(4 + 6v + 3 {v}^{3} ) - (5v + 8 {v}^{4} - 1)$

➼ $\: 4 + 6v + 3 {v}^{3} - 5v - 8 {v}^{4} + 1$

Combining like terms, we have

➼ $\: - 8 {v}^{4} + 3 {v}^{3} + 6v - 5v + 4 + 1$

➼ $\: - 8 {v}^{4} + 3 {v}^{3} + v + 5$
