Answer:
TheVolume of a Cylinder:
In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.
The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.
Answer:
The volume in m³ is 21.98m³ and the capacity in kiloliters is 21.98kl.
Step-by-step explanation:
Given:
Diameter of tank (d) = 2m
Height of the tank (h) = 7m
To find:
Volume of the tank (V) =?
Capacity of the tank in kiloliters =?
Formula:
V = πr²h
Solution:
The tank on the petrol lorry is in the shape of a cylinder with a diameter of 2m and a height of 7m.
Therefore, radius of the tank (r) = d/2 = 2/2 = 1m
We know that the volume of a cylinder is given as follows:
V = πr²h
Substituting the given values, we get
V = 3.14×1²×7
V = 21.98m³
Therefore, the volume of the tank in m³ is 21.98m³.
The capacity in kiloliters is 21.98kl.
