volume of sphere is = 4/3×π×r^3
where, r is the radius which is 10 units in this question
by substituting the value of r as 10,
we have the volume
= 4/3×π×10×10×10
= 4/3×π×1000
= 4000/3π (unit)^3
OR
if we take π=3.14 (approx)
the volume of sphere is
= 4000/3 × 3.14
= 424.628 (unit)^3
hope this helps!
