Surface Area of a sphere = 4π(r sq)
Given, volume of it, (4/3) π (r sq) = 606.375 mcube
∴ Surface Area of a sphere = 606.375 *3 = 1819.125 m sq.

Answer:
Step-by-step explanation:
Volume of the sphere = 606.375 m3
Volume of the sphere = 43πr3
⇒606.375=43×227×r3 (because, volume = 606.375 cm3)
⇒r3=606.375×3×74×22=144.703125
⇒r=5.25m
∴ Surface area of the sphere = 4r2 = 4×227×5.25×5.25 = 346.5 m2
