Question

How to find volume of sphere using vernier callipers?

Answer 1

1. Volume of the Sphere V = \frac{4}{3} \pi r^3 cm^3,

V= volume of Sphere, r = radius of Sphere

.

2.Least count of vernier calipers L.C = \frac{S}{N} cm,

S = value of 1 Main scale division , N = Number of vernier divisions.

3.Length (or) diameter of Cylinder = Main scale reading (a) cm + ( n*L.C ) cm.

n = vernier coincidence .

Answer 2

• Volume of the Sphere V = ,
