Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given by:
In this problem, the surface area is of 
cm², hence the radius in cm is found as follows:
r = 14 cm.
The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.

Answer:
D) 90%
Step-by-step explanation:
We have the percentages of students who go to public schools (84%), those who go to college (23%) and those who go to public college (17%).
We know that if you go to the public college, you go to the college, which means that it is a reduction with respect to the question, which is the percentage that goes to public schools and to the college (either public or private). This means that the percentage of public colleges must be subtracted from college because they are already included.
Therefore, the answer would be:
84% + 23% - 17% = 90%
90% of US students attend either public school or college, so the answer is D)
