Q5. Here is a vase in the shape of a cylinder
cm
The vace has a radius of 5 cm
There are 1000 cm of water in the vase.
Work out the depth of the water in the vase.
Give your answer correct to 1 decimal place

12.73

Step-by-step explanation:

solution,

here,

Given

radius of cylindrical vase is 5 cm

A vessel can fill 1000 cm of water it means

The volume of water vase is 1000 cu.cm

According to the formula ,

Volume of cylinder is - pi * r2 * h

or, 1000= (22/7)*(5*5)*h

or, 1000= 22*25*h/7

or, 1000*7= 550h

or, 7000= 550h

or, 7000/550= h

or, 12.73 cm = h

Therefore the depth of vase is 12.73 cm

thanks a lot for this question.

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.
