The radius of the sphere is 10 units. what is the approximate volume of the sphere?

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!

the answer is 31.27mph
