1.  The diameter of the sphere  =  10m

 

Vsphere  =  (4/3) pi ( diameter / 2 ) ^3  = (4/3) pi (10 / 2)^3  =

(4/3) pi (5)^3   ≈  523.59 m^3  =

524 m^3

 

 

2.  The diameter of the sphere  =  15 yd

 

SAsphere  =  4 pi  (diameter /  2 ) ^2   =  4 pi (15/ 2)^2   =

4 pi ( 7.5) ^2  ≈ 706.86 yd^2   =

707 yd^2
