Explanation:
_________________________________________

(1/2) π r² h = (1/2) * (3.14) * (30)² * 100 =  ?


                   (30)² * 100 = 30 * 30 * 100 = 90,000.


                    So, we have: (1/2) * (3.14) * (90,000) ;

                          → (1/2) * (90,000) = 45,000 ;

                       So, we have:  (3.14) * (45,000) = 141,300 units.
