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 !!!!
Ok thanks! :)
