Question

find the radius of sphere if its volume is 904.32 cubic cm (π = 3.14)

Answer 1

V of sphere=4/3 πr³
90432/100=4/3(314/100)r³
=> 90432/314(3/4)=r³
=>216=r³

r=6cm

here is your answer

Answer 2

The radius is 6cm

Given:

Volume = 904.78 $c m^{2}$

To find:

Radius of the sphere

Solution:

Volume of sphere is 904.32 cubic cm.

Let us take radius of sphere as R

As we know that,  volume of sphere is V$=\frac{4}{3} \pi r^{3}$

Putting R in place of r and putting V = 904.32 cubic cm we get

Equating the value of the Volume of the sphere with the formula, we get:

904.32 cubic cm. $=\frac{4}{3} \pi(R)^{3}$

Therefore, the radius of the volume of the sphere is  

$R=5.999\ \mathrm{cm} \approx 6 \mathrm{cm}$
