Answer:
V = A h.
Since the area of a circle = π r 2 , then the formula for the volume of a cylinder is:
V = π r 2 h.
Step-by-step explanation:
Answer: 525 cycles per second.
Step-by-step explanation:
The equation for inverse variation between x and y is given by :-
(1)
Given : The length of a violin string varies inversely with the frequency of its vibrations.
A violin string 14 inches long vibrates at a frequency of 450 cycles per second.
Let x = length of a violin
y= frequency of its vibrations
To find: The frequency of a 12 inch violin string.
Put
in equation (1) , we get
Divide both sides by 12 , we get

Hence, the frequency of a 12 inch violin string = 525 cycles per second.
