What is the diameter of a sphere with a volume of 3 litres?

Question

First correct answer gets an easy 10 points. Thanks guys...

JOS J · Accepted Answer

d = 1.7894

? · Answer

V = (4/3) pi R^3 = (4/3) pi (D/2)^3
so, if
V = 3 litres = 0.003 m^3,
 then

(4/3) pi (D/2)^3 = 3 . 10^(-3) m^3

D = 2 ( 9/4pi . 10^(-3) )^(1/3)  (so the cubic root)

D # 1.789 . 10^(-1) m so

D # 17.9 cm

hope it' ll help !!

Should be: d = (10*18^(1/3))/pi^(1/3) ~ 17.89400457879299 cm
