I have problem with the math function. I want to have this for the formula area= PI*radius^2, so i decided to use the math.h with the exp function but something is wrong. Can some one help me, thanks for your helpCode:/* Program 3: Write a program that reads in the radius of a circle and prints the circle's diamater, circumference, and area. Use the constant value 3.1459 fo pie. Do thes calculations in output statements. */ #include<stdio.h> #include<math.h> // math library #define PI 3.1416 int main(void) { float radius, diamater, circumference, area; printf("Please enter the radius of your circle: "); scanf("%f",&radius); //stores variable diamater = radius*2; // calculates radius circumference = PI*diamater; // calculates circumference area= (PI)*radius*(exp(2)); // to calculate exponent printf("Diameter: %0.2f\n", diamater); printf("Circumference: %0.2f\n", circumference); printf("Circle Area: %0.2f\n", area); return 0; }
