In a C program, translate the following into Chinese: What is the area of the inscribed circle of a right triangle?

In order to find the area of the inner circle of a right triangle, we have the formula for finding the radius of a right triangle, r = ( P B – H ) / 2.

Given P, B and H are the perpendicular, base and hypotenuse of the right triangle respectively.

The area of a circle is given by:

Area = π*r2

where π = 22 / 7 or 3.14, r is The radius of the circle.

Therefore the area of the inner circle will be given by the following formula,

Area = π* ((P B – H) / 2)².

In a C program, translate the following into Chinese: What is the area of the inscribed circle of a right triangle?

Example

#include
#define PI 3.14159265
int main() {
   float area,P = 3, B = 4, H = 5;
   area=(P + B - H) * (P + B - H) * (PI / 4);
   printf("Area = %f", area);
   return 0;
}

Output

Area = 3.141593
