Question

A sold sphere has volume 42pie. Find the radius of the sphere

Answer 1

Answer:

The Radius of sphere is 3.15 unit  

Step-by-step explanation:

Given as,

Volume of Sphere = 42 $\pi$    unit³

From the Volume of Sphere = $\frac{4}{3}$ $\pi$ r³

Where r is the radius of Sphere

So , 42 $\pi$  = $\frac{4}{3}$ $\pi$ r³

Or,  42  = $\frac{4}{3}$ r³

Or ,  r³ = $(\frac{42 \times 3}{4})$

Or,   r³ = 31.5

Or, Radius = $\sqrt[3]{31.5}$ = 3.15 unit

Hence the Radius of sphere is 3.15 unit   Answer
