Find the surface area of a sphere whose volume is 606.375
  • 1 answers

Yogita Ingle 5 years, 8 months ago

Volume of the sphere = 606.375 m3

Volume of the sphere = 4/3 πr3

⇒606.375=4 /3 × 22/7 × r3 (because, volume = 606.375 cm3)

⇒ r3 =(606.375× 3×7)/4 ×22 = 144.703125

⇒  r = 5.25m

∴ Surface area of the sphere = 4πr2 = 4×22/ 7×5.25 × 5.25 = 346.5 m2
