sphere

[humakhan]

Find the volume, to the nearest hundredth, of a sphere with a radius of 3 meters.

made a picture.....
then

V = 4/3 pi r^3
V = 4/3 pi (3)^3
V = 4/3 pi (27)
V = 4/3 ( 84.8230016)
V = 113.097335
V = 113.09 m^2

Yes.

cool

 

[tkhunny]

V = 4/3 pi (3)^3
V = 4/3 pi (27)
V = 4/3 ( 84.8230016)

More harrassment on precision.

(4/3)*pi*3^3 = 4*pi*3^2

It's just a slightly better way to go about it.
