Question

find the radius of a sphere whose volume is 113040 cubic meter (π=3.14)

Answer 1

Hello friend

Here is your answer!!!!!!!!!!!!!

_____________________________

Given:

Volume of a sphere= 113040 cu.m

We have to find it's Radius (r) = ??

We know that,

Volume of a sphere =

$\frac{4}{3} \pi \: r {}^{3}$


So by using this formula we will find the radius of the sphere.

So,by putting the given values we get,

$113040 = \frac{4}{3} \times 3.14 \times \: r {}^{3} \\ \\ \frac{113040 \times 3}{4 \times 3.14} = r {}^{3} \\ \\ \frac{28260 \times 3}{3.14} = r {}^{3} \\ \\ 9000 \times 3 = r {}^{3} \\ \\ r {}^{3} = 27000 \\ \\ r {}^{3} = 30 \: m$

Therefore, the radius of the sphere is

30m.

Any queries regarding this please ask.

Thanks...

Answer 2

Answer:

V of sphere=4/3 πr³

90432/100=4/3(314/100)r³

=> 90432/314(3/4)=r³

=>216=r³

r=6cm
