Answer :
The marble is a spherical shape so use the formulas for the sphere:
V= 4/3*π*r³ where r= radius, diameter is twice the radius
V= 4/3* π* (35/2)³
V= 22449.298 mm³
SA= 4*π*r²
SA= 4*π*(35/2)²
SA= 3848.45 mm²
V= 4/3*π*r³ where r= radius, diameter is twice the radius
V= 4/3* π* (35/2)³
V= 22449.298 mm³
SA= 4*π*r²
SA= 4*π*(35/2)²
SA= 3848.45 mm²
