How to find the height of a cylinder knowing the volume

Mathematics

Minchanka [31]3 years ago

Hello!

The formula for volume of a cylinder is:

V = pi × r^2 × h

You'll do the opposite to find the height:

H = V ÷ pi × r^2

As you can see, you need the volume and the radius to find the height.

A bag contains 25 kg of flour. A baker used 80% of it to bake bread. How much flour,in kg,remained ?​
SIZIF [17.4K]

Answer:

5 kg flour remains

Step-by-step explanation:

80% of the original 25 kg comes to 0.80(25 kg), or 20 kg.  We convert 80% to its decimal equivalent, 0.80, to get this result  

The amount of flour remaing is then (1.00 - 0.80)(25 kg), or 0.20(25 kg) = 5 kg.

5 kg flour remains.

Nadusha1986 [10]
