Answer: 38.79 cu. mm.

Step-by-step explanation:

Volume = 4/3π x r^3

= 4/3π x 2.1^3

= 4/3 x 22/7 x 9.261

= 38.79

Answer:

38.792 or 38.808

Step-by-step explanation:

Formula for Volume of Sphere = 4 x pi x 1/3 x r cubed

So,

if diameter = 4.2, then radius = 4.2 divided by 2 = 2.1

Now, volume =

4 x 22/7 x 1/3 x 2.1^3 = 38.808

But is you used 3.14 as pi,

then the volume = 38.792
