Question

Нужно найти объём цилиндра, если известно: образующая - 5 см радиус основания - 2 см

Answer 1

Объем цилиндра=площадь основания*высоту
Высота=образующей=5 см
Площадь основания=π*радиус²=4π (см²)
Объем=5*4π=20π (см³)

Answer 2

Calculating the Volume of a Cylinder

To calculate the volume of a cylinder, you can use the formula:

Volume = π * r^2 * h

Where: - π is a mathematical constant approximately equal to 3.14159 - r is the radius of the base of the cylinder - h is the height of the cylinder

Given that the radius of the base is 2 cm and the height is 5 cm, we can calculate the volume using the formula.

Calculation

Using the given values: - Radius (r) = 2 cm - Height (h) = 5 cm

We can calculate the volume using the formula: Volume = π * (2 cm)^2 * 5 cm

Result

Calculating the volume: Volume = π * 4 cm^2 * 5 cm Volume = 20π cm^3

Therefore, the volume of the cylinder is 20π cubic centimeters.
