Answer:
Volume of sphere is given by:
[tex]V = \frac{4}{3}\pi r^3[/tex] ......[1]
where
V represents the volume of sphere
r represents the radius of the sphere.
Value of [tex]\pi = 3.14[/tex]
Since, it is given that: Diameter(D) = 12.3 cm
Diameter(D) = 2r
[tex]12.3 = 2r[/tex]
Divide both side by 2 we get;
r = 6.15 cm
Now, substitute the value of r in [1] we get;
[tex]V = \frac{4}{3}(3.14)(6.15)^3[/tex]
Simplify:
V = 973.853732 cubic cm
Therefore, the exact volume of sphere is, 974 cubic cm
