Volume formula of cylinder: volume = π× the square of radius. (bottom area × height? S di h)

If π and R are used to represent the pi and radius of a cylinder, respectively

Explanation:

π is pi, which is generally 3. 14.

R is the radius volume of the cylinder bottom surface.

H is the height of the cylinder.

It can also be

v= 1/2ch×r

Half of lateral area × radius

Extended data:

There is a fixed line and a moving line in the same plane. When a plane rotates once around a fixed line, the surface formed by the moving line is called the rotating surface, the fixed line is called the axis of the rotating surface, and the moving line is called the generatrix of the rotating surface. If two planes perpendicular to the axis are used to cut the cylindrical surface, then the geometric figure surrounded by these two sections and the cylindrical surface is called a straight cylinder, which is called cylinder for short.

Pi (π) is the ratio of the circumference to the diameter of a circle, which is generally expressed by the Greek letter π and is a universal mathematical constant in mathematics and physics. π is also equal to the ratio of the area of a circle to the square of its radius. Accurate calculation of geometric shapes such as circle perimeter, circle area and sphere volume is the key value. In the analysis, π can be strictly defined as the smallest positive real number x satisfying sinx= 0.
