A round brass bar is 5m long and 14mm in radius calculate it's volume in cm

Answer 1

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.
