Help.

what is the approximate volume of the sphere if the surface area is 482.8mm? My answer is 997.53 but round and it'll be 998. Right?

Let's see, NSS

 

482.8  =  4pi r^2

 

482.8 / ( 4 pi )  =  r^2

 

√  [ 482.8 / (4 pi) ]   =  r ≈  6.2

 

So.....the volune  is  

 

(4/3) pi ( 6.2)^3  ≈ 998.3

 

Yep.....close enough...... ≈  998

 

Good job  !!!!
