Given a sphere with a diameter of 6 cm, find its volume to the nearest whole number.

mezya [45]

Answer:

Volume of the sphere is $1.13\times 10^{-4}m^3$

Step-by-step explanation:

It is given diameter of the sphere d = 6 cm = 0.06 m

Radius of the sphere

$r=\frac{d}{2}=\frac{0.06}{2}=0.03m$

We know that volume of the sphere is given by

$V=\frac{4}{3}\pi r^3$

Therefore ,

$V=\frac{4}{3}\times 3.14\times 0.03^3$

$=1.13\times 10^{-4}m^3$

Therefore volume of the sphere is $1.13\times 10^{-4}m^3$
