A spherical balloon has a 16 ​-in. diameter when it is fully inflated. Half of the air is let out of the balloon. Assume that the balloon remains a sphere. a. Find the volume of the​ fully-inflated balloon.
b. Find the volume of the​ half-inflated balloon.
c. What is the radius of the​ half-inflated balloon?

answer: b

step-by-step explanation:

i have no clue what you just said. write a question in english?

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
