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

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

$V=288\pi\ m^3$

W - 8 = 12 Select the correct answer.

Lelu [443]

Answer:

w = 20

Step-by-step explanation:

We need to solve the equation, to find the value of w:

w - 8 = 12 - we need to add 8 to both sides

w - 8 + 8 = 12 + 8 - the -8 and the +8 on the left hand side cancel out to give just w

w = 20

Does anyone know the answer? If so how did you get the answer.

Lana71 [14]

So if I remember correctly, so it tells you that the area is 96 ft and we have to find X. We already have two of the measurements and if 96 ft is the area (total) then we have to figure out the missing measurement that will add up with the other two to equal 96 ft. So what I did was that I added up 20 ft and 16 ft= 36 ft. So then you just minus 36 ft from 96 ft to get your answer (X) so X= 60 ft
