Answer:
radius=11.5
diameter=23
Step-by-step explanation:
The volume of a sphere is V=4/3 Pi r^3
We can use this to solve for the radius.
555.4= 4/3 (3.14)r^3
Solve for r how you would any other equation. Multiply 4/3 and 3.14.
555.4=4.187 r^3
Divide both sides by 4.187
132.65=r^3
To get rid of the ^3, find the cube root of both sides on a calcualtor.
r= 11.5
The diameter is the radius time two.
11.5 (2)=23.
Hope this helps!
Note: When I say both sides, I mean both sides of the = sign.

Answer:
12.5%
Step-by-step explanation:
I warn you, I'm not positive I'm correct.
First I added 8+10+6 and got 24
I divided that by 3 and got 8
I divided 100 by 8 because if you cross multiply 1/8 and x/100 you would get 8x = 100
100 ÷ 8 = 12.5
So I got 12.5%
Answer:
a = 9
Step-by-step explanation:
you can simplify the proportion to:
use cross- multiplication
8a = 72
a = 9
