a ball shaped like a sphere has a radius of approximately 2 and 1/8 inches. which is the best estimate of the volume of the ball

Respuesta :

So,

The formula for the volume of a sphere is:

[tex]V= \frac{4}{3}\pi r^3 [/tex]

Approximating 3.14 for pi and substituting the given values we get:

[tex]V= \frac{4}{3}(3.14) (2.125)^3[/tex]

[tex]V= \frac{4}{3}(3.14) (9.6)[/tex]

[tex]V= \frac{4}{3}(30.14)[/tex]

[tex]V = 40.19\ in.^3[/tex]
