Answer:

$\dfrac{4000\pi}{3}$ ft³

Step-by-step explanation:

First, let's figure out how to get the volume of a sphere from its surface area. If r is the radius of our sphere, then

The formula for a sphere's surface area is $A = 4\pi r^2$

The formula for a sphere's volume is $V=\frac{4}{3}\pi r^3$

So to get from area to volume, we have to divide the area by 3 and then multiply it by r. Mathematically:

$V=\frac{A}{3}r$

Before we solve for V though, we need to find the radius of our sphere. Thankfully, we're given the surface area - $400\pi$ ft² - so we can use the area formula to find that radius:

$A=4\pi r^2=400\pi\\r^2=100\\r=10$

And now that we have our radius, we can put it into our volume formula to find

$V=\frac{A}{3} r=\frac{400\pi}{3}(10)=\frac{4000\pi}{3}$ ft³

Express in simplified exponential notation. x3 • x5 =

Usimov [2.4K]

Answer:

x^8

Step-by-step explanation:

The applicable rule of exponents is ...

(x^a)(x^b) = x^(a+b)

Here you have ...

(x^3)(x^5) = x^(3+5) = x^8

Find three inequalities that are equivalent to 6x + 2x > 6 (x + 2)

lana66690 [7]

Answer:

x > 6

Step-by-step explanation:

6x + 2x > 6 (x + 2)

8x > 6 (x + 2)

8x > 6x + 12

-6x -6x

2x/2 > 12/2

x > 6
