Distance of n th bright fringe From central Fringe is given by
Also
Answer:
b
Step-by-step explanation:
the volume (V) of a cone is calculated as
V = πr²h ( r is the radius , h is the height )
here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then
V = π × 6² × 22
= π × 36 × 22
= π × 792 ( cancel 3 and 792 by 3 )
= π × 264
≈ 829.4 m³ ( to the nearest tenth )
