Question

write one method to measure the diameter of sphere? a​

Answer 1

Answer:

Call the diameter d, (d=2r where r is the radius of the sphere). Call the distance from the observer to the centre of the sphere D; measure or calculate D. tan θ = 2r/D from which, by substituting the determined values for tanθ and D, out pops the value for 2r (=d).

Answer 2

Answer:

There are multiple methods to find the diameter (d) of a sphere from the volume (V). One of the methods is to substitute V directly into the formula, d = (6V/π)(1/3). Alternatively, we can substitute V into the volume of a sphere formula, V = (4/3) π r3, solve for r, and double the radius (r) to find the diameter.
