Answer 2

Answer:

Voume of the cube will be 5.13$cm^{3}$

Explanation:

In this question

we have been given that,

Diameter of sphere is 2.14cm

We need to calculate the volume of the sphere

According to the question

Diameter$\ =\ Radius\times$

Therefore Radius = $\frac{Diameter}{2}$

Radius = $\frac{2.14}{2}$

Radius=1.07cm

Volume of the Sphere = \frac{4}{3}\times \pi\ r^{3}[/tex]

Putting the values Taking $\pi\ =\ \frac{22}{7}$

Volume of the Sphere = $\frac{4}{3}\times \frac{22}{7}\times (1.07)^{3}$

Volume of the Sphere = $\frac{4}{3}\times \frac{22}{7}\times 1.225043$

Volume of the Sphere = 88×0.058335381

Volume of the Sphere = 5.1335135238

Taking it two significant figures we get,

Volume of the sphere as 5.13$cm^{3}$
