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.
