(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

the volume v=(4/3)(pie symbol 3.14..)r of a spherical balloon changes with the radius

a)at what rate does the volume change with respect to radius when r= 2ft?

b) by approximately how much does the volume increase when the radius changes from 2 to 2.2ft?

2. Relevant equations

v=(4/3)(pie symbol 3.14..)r

sorry, couldn't find the pie symbol to multiply the r with in this equation

3. The attempt at a solutionfor part a i tried to plug in 2 or the r in the equation and then divide by 2

for part b i tried subtracting the equation when r is substituted for 2 from when the r is substituted for 2.2
