Answer:

Below.

Step-by-step explanation:

The problem would look like this:

12 3/8 / 5 1/2

My math teacher told us to write it like a normal division problem.

12 3/8 ÷ 5 1/2

One way to solve is to turn both fractions into improper fractions, so..

12 3/8

So multiply 8 x 12 = 96 + 3 = 99/8

Then, 5 1/2, 2 x 5 = 10 + 1 = 11/2

99/8 ÷ 11/2, 99 ÷ 11 = 9, 8 ÷ 2 = 4,

So your answer would be 9/4, which is an improper fraction. To simply, just divide 9 by 4, and you would get 2 1/4 (mixed number).

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

You can cancel out 99 and 11 to 9 and 1 as they are multiples of eac hother and you can do the same for 8 and 2 to 4 and 1

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
