The radius of the large sphere is times longer than the radius of the small sphere. How many times the volume of the large sphere is the volume of the small sphere?

27

Step-by-step explanation:

Let the radius of the smaller sphere is x.

Then the radius of the larger sphere is 3x.

The volume of a sphere is given by

Hence, the volume of the smaller sphere is

And the volume of the larger sphere is

Divide both volumes, we get

Hence, the volume of the smaller sphere is 27 times smaller than the volume of the larger sphere.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
