A point source emits sound waves isotropically. The intensity of the waves 6.00 m from the source is `4.50 xx 10^(-4) W//m^2` . Assuming that the energy of the waves is conserved, find the power of the source.

Explanation

To find the power of a point source emitting sound waves isotropically, we can follow these steps:

### Step 1: Understand the relationship between intensity, power, and distance
The intensity (I) of sound waves from a point source is given by the formula:
\[ I = \frac{P}{A} \]
where \( P \) is the power of the source and \( A \) is the surface area over which the power is distributed. For a point source, the sound waves spread out uniformly in all directions, forming a sphere.

### Step 2: Calculate the surface area of the sphere
