The volume of a sphere is 4 x 3.14 x r^3/3

The answer would be C. 165.... let me know if this helped :)
aaaaaaaphhh

Answer:165


Step-by-step explanation: The volume of Earth: VE=4/3 · 6371³ π  

The volume of Pluto:  VP=4/3 · 1161³ π

(4/3 · 6371³ π ) : (4/3 1161³ π )= ( 5.48751 · 1161 )³ : 1161³ = 5.48751³

=165.24
