    I'm guessing you want the circumference and area of a circle that has a radius of 5 meters?

    circumference = 2 * PI * r

    circumference = 2 * PI * 5

    circumference = 10 * PI = 31.14159 meters

    area = PI * r^2

    area = 3.14159 * 5^2

    area = 3.14159 * 25

    area = 78.53982 square meters
