The formula of the volume for a cylinder is pi*r^2*h. Given the diameter of 1 inch and height/length of 2.5 inches, the volume is calculated by:

V = pi*(0.5^2)*2.5 = 1.9625 in^3
 the cork density is 0.26 g/mL, since the units of the volume is in^3, convert to cm^3 or mL:
1.9625 in^3 * (2.54cm/1in)^3 = 32.16 cm^3

So, the mass of the cylindrical cork is 0.26 g/mL * 32.16 cm^3 = 8.36 g
