If the radius of a sphere i'd tripled, does the volume also triple? explain.

If the radius of sphere is tripled, then volume does not triple. But volume increases by a factor of 27

Solution:

Given if the radius of sphere is tripled, whether the volume of sphere triples or not

The volume of sphere is given as:

Where "r" is the radius of sphere

When radius is tripled:

r = 3r

Let be the volume when radius is tripled

volume when radius is tripled = 27 times volume of sphere when radius is "r"

Therefore, if the radius is tripled the volume increases by a factor of 27

So the volume does not gets tripled

x = 12

y = 1

for the points!

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
