Question

A sphere with a radius of 1.7 cm has a volume of:

Answer 1

Given,

Radius of the sphere = 1.7 cm

To find,

Volume of the given sphere.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Volume of a sphere = ⁴/₃ × π × (radius)³

By, putting the given values, we get :

So, Volume of the given sphere :

= [⁴/₃× π × (1.7)³] cm³

= [⁴/₃ × ²²/₇ × (1.7)³] cm³

= 20.58 cm³

[This will be considered as the approximate final answer. And, the unit of given radius is cm, so the unit of volume which we have used is cm³.]

Hence, the volume of the sphere will be 20.58 cm³

Answer 2

Given:

Radius of sphere = $1.7$ cm

To find:

Volume of the sphere

Formula used:

Volume of the sphere = $\frac{4}{3} \pi r^{3}$ cubic units

Step-by-step explanation:

Volume of sphere = $\frac{4}{3}$ × $\frac{22}{7}$ × $(1.7)^{3}$

⇒ $\frac{4}{3}$ × $\frac{22}{7}$ × $4.913$

⇒ $\frac{88}{21}$ × $4.913$

⇒ $20.587$ $cm^{3}$

Answer:

The volume of sphere = $20.587$ $cm^{3}$
