Question

If student is performing an experiment on vernier caliper to find
volume of sphere .If student get value of diameter as 2.54 cm ,2.52 cm,2.56 cm ,2.55cm and 2.56 cm then find mean radius and also find its volume.(take π =3.142 )​

Answer 1

Given,

Mean Diameter = Sum of all diameter observed/No. of diameter observed

= (2.54+2.52+2.56+2.55+2.56)/5 cm

= 12.73/5 cm

= 2.546 cm

Mean Radius = 2.546/2

= 1.273 cm

Volume = 4/3πr³

= 1.333*3.142*1.273*1.273*1.273 cm³

= 8.64 cm³

I hope this helps.
