The surface area of a sphere is 275.56 1 cm? What is the approximate volume of the sphere?

skad [1K]

Answer:

$V=430.19\ cm^3$ or $V=136.93\pi\ cm^3$

Step-by-step explanation:

The surface area of a sphere is:

$A_s=4\pi r^2$

Where r is the radius of the sphere

In this case we know that $A_s = 275.561\ cm^2$

$4\pi r^2=275.561$

We solve the equation for r

$4\pi r^2=275.561\\r^2 = \frac{275.561}{4\pi}\\\\r=\sqrt{ \frac{275.561}{4\pi}}\\\\r=4.683\ cm$

Now we know the radius of the sphere.

The volume of a sphere is:

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

We substitute the value of the radius in the formula

$V=\frac{4}{3}\pi (4.683)^3$

$V=430.19\ cm^3$

What is the answer to 2x-6(2)?

ololo11 [35]

2x-6 (2) is your equation. follow these steps, and you have to distribute 6 into 2 like this: 2x-12. you get negative 12 because -6 x 2 =-12. now you divide -12 by 2 which is -6. So -6=x
