Find the diameter of the sphere whose volume is 381$$\frac{6}{7}$$ m³.​

Volume of the sphere = 381$$\frac{6}{7}$$​ m³ =$$\frac{2673}{7}$$ m³  

Volume of the sphere = $$\frac{4}{3}{\pi}r^3$$ 

$$\frac{4}{3}{\pi}r^3$$= $$\frac{2673}{7}$$​ m³

r³ = $$\frac{2673×7×3 }{7×22×4}$$

​$$\left( \frac{d}{2} \right)^3 = 91.125$$

d³ = 729 m

d = 9 m
