Write a program in C, enter the radius and height, and find the volume of a cylinder

#include

#define pi

int main()

float r,v,h;

printf("Please enter the radius and height:");

scanf("%f%f",&r,&h);

v=pi*r*r*h;

printf("The volume of the cylinder is %2lf",v);

return 0;

I'll give it a try.,I've been learning C++ lately.,C language is not familiar.,Hehe include.""

int main()

float r,h,v;

printf("Please enter the radius and height of the cylinder");

scanf("%f%f",&r,&h);

v=;printf("The volume of the cylinder is %f",v);

return 0;

#include ""

define pi to modify its precision.

void main()

float r,h,v;

printf("Please enter the radius and height of the cylinder");

scanf("%f%f",&r,&h);

v=pi*r*r*h;

printf("The volume of the cylinder is %f",v);

Correcting the error] Pomeranz is basically correct, but there is a small error, and there must be a mistake in compiling.

In the output, in the printf function, you only need to write the name of the variable. You don't need to take the address "&".

Reminder] 1Some C language compilation environments do not support Chinese characters, you can use pinyin or English instead of Chinese characters.

2.When entering two parameters in a row, each variable needs to be determined by pressing enter. In this case, you need to enter the radius and hit enter. Otherwise, the input value will not be passed correctly to the corresponding parameter.

Revision] include""

int main()

Define floating-point variables*

float r,h,v;

Prompts the user for a variable*

printf("Please enter the radius and height of the cylinder");

Enter two variables*

C language input radius to find the circle area and the perimeter of the dissipation as shown in the following figure:

The diameter and length of the radius of the inner circle of the same circle are always the same, and the circle has an infinite number of radii bridges and countless diameters. A circle is an axisymmetric, center-symmetrical figure.

The axis of symmetry is the straight line where the diameter is located. At the same time, the circle is a "positive infinite polygon", and "infinity" is just a concept. The circle can be seen as being infinitely smaller.

When the number of sides of the polygon increases, the shape, circumference, and area are closer to the circle.

1. In the same circle or equal circle, the circumferential angle of the equal arc.

equal to the central angle of the circle it opposes.

(the circumferential angle is on the same side as the central angle of the chord).

2. If the length of an arc is twice that of another arc, then the circumferential and central angles of the arc are twice that of the other arc.

3. The midpoint M of the chord PQ in the circle O, the passing point M is either the two strings AB, CD, the chord AD and BC intersect PQ at X and Y respectively, then M is the midpoint of XY.

C language input radius to find the circle area pure dust and perimeter as shown in the following figure: the diameter of the circle within the same circle, the length of the radius of the collapse is always the same, and the circle has several radii and countless diameters.

Suppose the variable that receives the value of the radius of the rent is r, pi is pi, and the area of the circle is defined as s, and the perimeter is defined as c.

#include

#define pi

int main()

float r,v,h;

printf("Please enter the radius and height:")

scanf("%f%f",&r,&h);

Socks v=pi*r*r*h;

printf("The volume of the cylinder is %2lf",v);

return 0;

t<>

** As follows: int main().

float r,h,s;

scanf("%f"Argument Finish, &r);

scanf("%f",&h);

s=2*printf("The surface area is %f",s);

return 0;

Summary. Hello, glad for your question, now that we know the volume formula for the sphere, all we have to do is define the variables, construct the expression and output. Here the pi constant can be defined or obtained.

Hello, I'm glad to answer your question, now that you know the volume cavity formula for the sphere, all you have to do is define the variables, construct the expression, and output it. Here the pi constant can be defined by yourself, or you can obtain it by passing.

C language: program the radius of the input circle, calculate the area of the circle and output, and keep 2 decimal places when output.
