please fine

a) volume of cavity

_________cm^3

b) volume of entire object calculation

_________cm^3

c) density of cylinder calculation

  _________kg/m^3

Answer 1

here,

a)

volume of cavity , Vc = pi * (d/2)^2 * h

Vc = pi * ( 0.023/2)^2 * ( 0.004)

Vc = 1.66 * 10^-6 m^3

Vc = 1.66 cm^3

b)

volume of entire object , V = Volume of cyclinder - volume of cavity

V = pi * (D/2)^2 * H - 1.66 * 10^-6 m^3

V = pi * ( 0.043/2)^2 * 0.014 - 1.66 * 10^-6

V = 1.87 * 10^-5 m^3

V = 18.7 cm^3

c)

mass of cyclinder , m = 45.2 g = 0.0452 kg

density , d = mass /volume

d = 0.0452 /( 1.87 * 10^-5)

d = 2.42 * 10^3 kg/m^3
