Calcular el volumen en m3 de la esfera en el que el área de uno de sus círculos maximos es 36pim2

Strike441 [17]

Answer:

The volume of the sphere is $V=288\pi\ m^3$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Calculate the volume in m^3 of the sphere in which the area of one of its maximum circles is 36pi m^2

we know that

The radius of the maximum circle in the sphere is equal to the radius of the sphere

Step 1

Find the radius of the maximum circle

The area of the circle is

$A=\pi r^{2}$

we have

$A=36\pi\ m^2$

substitute and solve for r

$36\pi=\pi r^{2}$

Simplify

$36=r^{2}$

take the square root both sides

$r=6\ m$

Step 2

Find the volume of the sphere

The volume of the sphere is

$V=\frac{4}{3}\pi r^{3}$

substitute the value of r

$V=\frac{4}{3}\pi (6)^{3}$

$V=288\pi\ m^3$

A quadratic equation of the form 0=ax^2+bx+c has a discriminant value of -16. How many real numbers solutions does the equation

alina1380 [7]

Answer: 0

Step-by-step explanation:

The disciminant \Delta tells you how many real solutions a quadratic equation has, depending on its sign:

\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}

If two adjacent angles have their exterior sides in perpendicular lines the two angles are?

Agata [3.3K]

If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular. Exterior and interior angles sum up to 180 degrees. Hence if the exterior angle is perpendicular, then the interior angle should also be perpendicular in order to sum up to 180 degrees.
