Question

A goldfish bowl is shaped like a sphere and has inside radius of 15 cm how much water is needed to fill the bowl?​

Answer 1

The water needed to fill the bowl is 14.142 l

Given:

The radius of the spherical bowl is 15cm

To find:

The volume of the bowl.

Solution

The radius of the spherical bowl is 15cm.

To find how much water is needed to fill the bowl with water we have to assume that the bowl is completely spherical. To answer this, we have to find the volume of the bowl.

We know;

The volume of a sphere is 4/3π$r^{3}$

So, Water needed=4/3×22/7×15×15×15

=14,142.8571$cm^{3}$

Now, 1l=1000$cm^{3}$

14142.8571$cm^{3}$= 14.142l

So, 14.14 l of water is needed.

Answer 2

Answer:

Water needed to fill the bowl is 14.142 L.

Step-by-step explanation:

As per the data given in the question,

We have,

Radius of shperical bowl = 15 cm

Water to be filled= volume of sphere

volume of sphere= $\frac{4}{3}\pi r^{3}$

$=\frac{4}{3}\times\frac{22}{7} \times15\times15\times15\\= 14,142.8571 \:cm^{3}$

since,

1L= 1000 cm³

So, water needed to fill the bowl is 14.142 L.
