Let radius of hemisphere = $$r$$ cm
Volume of hemisphere = $$\frac{2}{3}\times\pi r^3$$
=> $$\frac{2}{3}\times\frac{22}{7}\times(r)^3=5749.33$$
=> $$(r)^3=5749.33\times\frac{21}{44}$$
=> $$(r)^3=274.399\equiv2744$$
=> $$r=\sqrt[3]{14\times196}=14$$ cm
$$\therefore$$ Diameter = $$2\times14=28$$ cm
=> Ans - (D)
