Answer:
its 22 because it is going by 3
Answer:
1/5
Step-by-step explanation: 4
"4 to 20" is in itself a ratio. This can be written as 4:20 or as -------
20
and this last result reduces to 1/5.
The answer is thirteen (13). You can use the Pythagorean theorem to figure it out.
a^2+b^2=c^2
5^2+12^2=c^2
25+144=c^2
169=c^2
13=c
To put it another way, that ratio exists, no matter what distance units you use to express lengths, such as the radius of the Earth, but using different units will result in a different numerical part.
<span>You can't, for instance, say the the radius of the Earth is 3960, and leave it at that. </span>
<span>If someone comes along who's measuring everything in km, he'll tell you that it's 6373. </span>
<span>Or if he's using meters, he'll say it's 6,373,000. </span>
<span>Or in yards, 6,969,600. </span>
<span>So r = 3960 mi </span>
<span>And as others have said, the area, A, and volume, V, of a sphere, in terms of its radius, are </span>
<span>A = 4πr² </span>
<span>V = 4πr³/3 </span>
<span>so that the area to volume ratio is </span>
<span>A/V = 3/r </span>
<span>So the answer is </span>
<span>3/(3960 mi) = (1/1320) /mi. </span>
