A sphere has a diameter of 24 units. What is its volume in cubic units?
NNADVOKAT [17]
Ummm... I explained the whole process earlier, and was mistakenly issued for plagiarism. Which really sucks, because it took forever to type and format all of those formulas and steps.
Here's the shortened version...
V=4/3 \pi r^{3}
d (diameter) = 2r
so 24/2 = 12
plug in...
You should get approx. 7234.56, and don't forget to label it appropriately, it should be units cubed.

What is (-4/9)*(5/8)?
Firlakuza [10]

Answer:

-0.27777777777

or

-5/18

Step-by-step explanation:

It's

<u>-4</u>    x     <u>5</u>

9            8

(sorry.. don't know how to write fractions...)

You multiply the numerators by numerators (the top numbers) and denominators by denominators (bottom numbers)

-4 x 5 equals -20.

9 x 8 equals 72

That would be -20/72, which simplifies to -5/18.

*top times top, bottom times bottom
