   A right circular cylinder has a height of 2214 ft and a diameter 225 times its height. What is the volume of the cylinder?     

 

   V  = π r² h     

 

   r  =  (1/2) • (diameter)  =  (1/2) (225 • 2214)  =  249,075     

 

   V  =  (3.1416) (249,075²) (2214)     

 

   V  =  (3.1416) (62,038,355,625) (2214)     

 

   V  =  431,507,931,441,741 ft³
