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

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

$V=288\pi\ m^3$

Pls help I dont understand. Find the inverse of this function.

lisov135 [29]

In the inverse we replace the place of x by y .

$g(x) = \sqrt[3]{x} - 3 \\ \\ x = \sqrt[3]{y} - 3 \\ \sqrt[3]{y} = x + 3 \\ y = {(x + 3)}^{3} \\ y = {(x + 3)}^{2} (x + 3) \\ y = ({x}^{2} + 6x + 9)(x + 3) \\ \\ y = {x}^{3} + 6 {x}^{2} + 9x + 3 {x}^{2} + 18x + 27 \\ \\ y = {x}^{3} + 9 {x}^{2} + 27x + 27 \\ \\ \\ g(x)^{ - 1} = {x}^{3} + 9 {x}^{2} + 27x + 27$

I hope I helped you^_^

Solve the equation for x 25=1/x

Mkey [24]

Answer:

x = 1/25

Step-by-step explanation:

Solve for x:

25 = 1/x

25 = 1/x is equivalent to 1/x = 25:

1/x = 25

Take the reciprocal of both sides:

Answer: x = 1/25
