Question

The radius of a sphere measured separately yields values 4.1m, 4.2m and 4.3m, then the arithmetic mean radius will be?​

Answer 1

Answer:

hey here is your answer for your question

pls mark it as brainliest

Explanation:

so the three different measures values of radius of particular sphere are 4.1 cm,,4.2 cm,,4.3 cm

so here as there are 3 values

arithmetic mean would be,,

sum of total values/ total values

ie 4.1 cm+4.2 cm+4.3 cm/3

ie 12.6 cm/3

=4.2 cm

hence arithmetic mean radius of sphere would be 4.2 cm
