Question

Длина окружности основания цилиндрической бочки 36п дм а высота 12дм сколько воды вмещает бочка

Answer 1

Ответ:

3888π дм³

Объяснение:

Надо найти объем V;  V=Sосн*h.

Sосн=πR²;  длина окружности с=2πR=36π;  R=36π:2π=18 дм.

Sосн=π*18²=324π

V=324π * 12=3888π дм³

Answer 2

Calculating the volume of a cylindrical barrel

To calculate the volume of water a cylindrical barrel can hold, we need to know its dimensions. The question states that the diameter of the barrel's circular base is 36π dm (decimeters), and its height is 12 dm.

To find the volume of a cylinder, we use the formula:

`Volume = πr^2h`

Where:

- r is the radius of the circular base - h is the height

Since the diameter given is 36π dm, the radius is 36π/2 = 18 dm.

Plugging into the formula:

`Volume = π(18)^2 * 12` `= π * 324 * 12` `= 3816π dm^3`

Therefore, the volume of water this barrel can hold is 3816π dm^3.
