Answer:
The volume of a sphere is 2/3 times the volume of a similar cylinder
Scale factor : 2/3
Step-by-step explanation:
Let us consider a sphere of radius r. The volume of the sphere will be given as

Similarly, let us consider a cylinder with its height being twice the radius of the sphere. We will have its volume given as:

but h = 2r
Hence we have

We can divide the two volumes to get a constant that links them together

this will give us 2/3
Hence the scale factor for Vol sphere: Vol cylinder is 2/3
Answer:
I did the whole graph myself so you can just couple it down lol ;)
Answer:
x/y = 3/8
Step-by-step explanation:
y = 4/5 = 8/10, so ...
x/y = (3/10)/(8/10) = 3/8

One way to divide fractions is to make them have the same denominator. Then their ratio is the ratio of their numerators.
