Question 132978
Since the diameter is 4,000 miles, this means that the radius is 2,000 miles (just take half of 4,000)



So {{{r=2000}}}





{{{V=(4/3)pi*r^3}}} Start with the volume of a sphere formula



{{{V=(4/3)(pi)*(2000)^3}}} Plug in {{{r=2000}}}



{{{V=(4/3)(pi)*8000000000}}} Cube {{{2000}}} to get {{{8000000000}}}



{{{V=(4/3)25132741228.7183}}} Multiply {{{pi}}} and  {{{8000000000}}} (you can use 3.14 for pi) to get {{{25132741228.7183}}}



{{{V=33510321638.2911}}} Multiply {{{4/3}}} and  {{{25132741228.7183}}} to get {{{33510321638.2911}}}



So the volume of the sphere with a radius of 2000 miles is 33,510,321,638.2911 cubic miles




This means that volume of Mars is 33,510,321,638.2911 cubic miles
