Answer:
Step-by-step explanation:
Wave velocity of the sound = frequency * wavelength.
The frequency and wavelength depend on the medium through which the sound passes and they are both greater in the guitar string than in air as the string is denser than the air. So the sound travles faster through the guitar string.
2 cm = 5 feet
1 cm = 2.5 feet
9 cm = 9 * 2.5 = 22.5 feet by
4 cm = 4 * 2.5 = 10.0 feet
The answer
if Marco wants to create a new circle using GX as a radius,
so GX = r = 10 cm + 16 cm = 26 cm
the area of a circle is
A = pie x r², so the new circle's area should be A = pie x 26² = 676 pie cm²
the true answer is
