Thread: Cannot resolve error

I'm new in C programming and i have this assignment.

Prompts the user to enter the radius of the circle. A real number
is expected.

(b) Prints on the screen the circumference of the circle in the
following format:
“The circumference of a circle with radius x ft is equal to x.xx ft.”

(c) Prints on the screen the area of the circle in the following format:
“The area of a circle with radius x ft is equal to x.xx sq. ft.”

The results should be printed to a precision of 2 decimal digits.

Code:

#include<stdio.h>
void main()
{
int r;
int pi=3.14;
float cir,area;
printf("/n enter the radius of the circle");
scanf("%d",&r);
cir=2*pi*r;
area=pi*r*r;
printf("the circumference of the circle is%d", cir);
printf("the area of the circle is%d", area);
}

This is my code so far. It comes out with 2 errors on the last two lines. If someone could help me resolve these and get the program running that would be great.
