Find the volume of the cylinder.
Either enter an exact answer in terms of or use 3.14 for pi. with a radius of 4 and a height of 10
HELP PLEASE

V= 160pi or V= 502.65

Step-by-step explanation:

V = pi × r^2 × h

V = pi × (4)^2 × 10

V = pi × 16 × 10

V= 160pi or V = 502.65

y=x+2 hope this jdjxhdnzbdjdo

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
