The distance of the sound from the tuba is 4.82 m.
Area of the tube
The area of the tuba is calculated as follows;
I = P/A
where;
- I is intensity of sound
- P is power
- A is area
A = P/I
A = 0.35 / (1.2 x 10⁻³)
A = 291.67 m²
Distance of the sound
Area = 4πr²
[tex]r = \sqrt{\frac{A}{4\pi} } \\\\r = \sqrt{\frac{291.67}{4\pi} } \\\\r = 4.82 \ m[/tex]
Thus, the distance of the sound from the tuba is 4.82 m.
