Answer:
452.57 cm² and 1877.33 cm³, respectively.
Step-by-step explanation:
Surface Area of the outer sphere shell = 4πr²
=> 4×(22/7)×6²= 88×36/7 = 452.5714285714286 cm²
=> Approx. = 452.57 cm²
Volume of the inner sphere = 4πr³/3 = 4×(22/7)×4³/3= 88×64/3=1877.333....
=>Approx.= 1877.33 cm³

volume of spare is wrong answer the correct answer is 636 point 95 cm cube
inner surface area is wrong
I CLEARLY wrote, OUTER surface area and INNER volume...
you have to also find the volume of the metal contained in a cell the outer diameter of a spherical shell is 12 CM and its inner diameter is 8 cm
didn't I just find that?
