Nancy is asked to use her calculator to find the volume of a cylindrical canister that has a radius of 10.55 cm and a height of 12.56 cm.
which answer is the most accurate?
volume of a cylinder can be calculated using the following equation: v=πr2h
a. 4377 cm3 c. 4380 cm3 b. 4379 cm3 d. 4392 cm3

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

the maxium height is 34m/s
