A round brass bar is 5m long and 14mm in radius calculate it's volume in cm
Answers
GPT 3.5
To calculate the volume of the round brass bar, we can use the formula for the volume of a cylinder:
V = πr^2h
Where:
V = Volume
r = Radius
h = Height (or Length in this case)
Given that the radius is 14mm, we first need to convert it into cm:
14mm = 1.4cm
Now we can calculate the volume:
V = π(1.4cm)^2 * 500cm
V = π(1.96cm^2) * 500cm
V = 3.14 * 1.96 * 500
V = 3077.6 cm^3
Therefore, the volume of the round brass bar is 3077.6 cm^3.
