Answer:

About 904.78 inches^3

Step-by-step explanation:

A beach ball is a sphere. The volume of a sphere can be found using:

v=4/3 r^3 π

First, we have to find the radius. The radius is half of the diameter, or

r=d/2

We know the diameter is 12 inches, so we can substitute 12 in for d.

r=12/2

r=6

Now we know the radius, and can substitute it in for r.

v=4/3 r^3 π

v= 4/3 6^3 π

Evaluate the exponent

v=4/3 216 π

Multiply all the numbers together

v=904.778684234

So, the volume is about 904.78 inches^3

A person has a weekly salary of x and gets a raise of 32% which is worth 50$ what is the weekly salary?

GuDViN [60]

Answer:

$156.25

Step-by-step explanation:

A good strategy in my opinion is the "finders" strategy

50$ = 32%

x = 100%

First Multiply 100 by 50

100 x 50 = 5,000

Then Divide 5,000 with 32

5,000/32 = $156.25

If you want to check, then...

156.25 x 32 = 5,000

x = $156.25

Hope this helps!

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches ( $1\,ft = 12\,in$ ) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:
