Question

The diameter of solid cylinder measured with Vernier caliper is 2.02 cm and its length to be 3.52 cm,find its volume to the possible accuracy.

Answer 1

Answer

hope u understand this answer

The volume of the cylinder = the surface area of either end of the cylinder x the length (L) of the cylinder.

The surface area of either end of the cylinder = Pi

x (d/2)^2 = 3.14 x (2.02cm/2)^2 = 3.14 x (1.01cm)^2 = 3.14 x 1.02cm^2 = 3.20cm^2

Volume of cylinder = surface area of either cylinder end x L = 3.20cm^2 x 3.52cm = 11.27cm^3.

The volume of the cylinder = 11.27 cubic centimeters.
