I can't speak to the cactus specifically, but any sphere has a surface area of
![4\pi r^2](https://tex.z-dn.net/?f=4%5Cpi%20r%5E2)
and a volume of
![\frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3)
, so the area-to-volume ratio wold be
![\frac{4\pi r^2}{ \frac{4}{3}\pi r^3 } = \frac{3(4\pi r^2)}{4(\pi r^3)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%5Cpi%20r%5E2%7D%7B%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%20%7D%20%3D%20%5Cfrac%7B3%284%5Cpi%20r%5E2%29%7D%7B4%28%5Cpi%20r%5E3%29%7D)
![= \frac{3\pi r^2}{\pi r^3}\\\\ = \frac{3}{r}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3%5Cpi%20r%5E2%7D%7B%5Cpi%20r%5E3%7D%5C%5C%5C%5C%0A%3D%20%5Cfrac%7B3%7D%7Br%7D%20%20%20)
Where <em>r</em> is the radius of the sphere.
(5b+xyz_6) xyx+ That is the right answe Im super positive it may seem wrong bit I got. you...
You are correct for all of them,
Precision goes up as you have more decimals. It gives you a more accurate measurement regardless of what it is measuring.
A line graph measures two variables, the X and the Y, and how they change based off of one another
And an educated guess would usually based on previous trends or results
Since there is no graph presented, I will give an example. For instance you are given, 2n is greater than 30 and 5n is less than 100 and you are asked to find the value of n. This is an example of an inequality problem. You are given 2n is
greater than 30 and 5n is less than 100. You are asked to find for the value of
n. You need to know that greater means this sign ‘>’ and lesser means ‘<’
sign. So if you have 2n is greater than 30, this is equal to 2n>30 and 5n is
less than 100 is 5n<100. The ‘and’ means equal sign ‘=’. So,
2n>30+5n<100
2n-5n

Answer:
110.5mm
Step-by-step explanation:
Formula : a = hb/2
a = 13(17)/2
221/2 = 110.5
