By definition, the volume of a sphere is given by:
Where,
r: is the radius of the sphere
The radius of the sphere is:
Where,
d: diameter of the sphere
Substituting values we have:
Then, the nolumen is given by:
Answer:
the volume of the sphere is:
65.4 in³
I'm going to write out the work and take a pic. hope this helps you understand if not, feel free to ask me Q's! :)
Let's pick some simple points with which to set up an example for ourselves for this. Let's let the smaller radius be 1, and the larger, twice that, be 2. The radius itself is a single unit measure; in other words, it's measured as inches, feet, cm, etc., while the volume is a cubed measure. Volume is measured in inches cubed, feet cubed, cm cubed, etc. Therefore, if we have the radii measuring 1:2, we simply cube those single unit measures to find the ratio of their volumes. 1 cubed is 1, and 2 cubed is 8. So your answer for this is 1/8.
Im not too sure so dont take my word.
But if you're rounding the fraction to half or whole.
I would round down from 8/14 , to 7/14.
Which 7/14 simplified is 1/2
Your answer is 7/14 i believe
Answer:
1/24, 1/16, 1/12, 1/10, 1/8, 1/6, 1/4, 1/3, 1/2
Step-by-step explanation:
If you have this many fractions and they all have the same numerator, then the smallest number will have the biggest denominator and the biggest number will have the smallest.
So when you have all numbers with the same numerator and you're trying to put them in order from smallest to greatest, it's like putting the denominators in order from largest to smallest. (So, the 1/24 is the SMALLEST and the 1/2 is the BIGGEST.
