Find the volume of a cylinder whose base diameter is 8cm and the height is 3.5cm.

In order to calculate the volume of a cylinder, it is necessary to multiply its base area by its height:

V = S main h.

The base area of this cylinder is calculated as the product of the square of the radius and π (which is 3.14):

Sbn = πr2.

To do this, you need to find the radius of the base, which is half the diameter:

r = d / 2;

r = 8/2 = 4 cm.

Let’s move on to calculating the base area:

Sb = 3.14 16 = 50.24 cm2.

Now you can find the volume:

V = 50.24 3.5 = 175.84 cm3.

Answer: the volume of this cylinder is 175.84 cm3.
