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.
