to get the circumference of a circle you must multiply pi times diameter so say the circle's diameter was 8, you would do you 8 x pi (3.14 in this case) = 25.12 . that would be the circumference. the formula is circumference = pi (3.14) x diameter !
here's some extra information, to get the area of a circle you have to multiply pi and the radius of the circle squared. so say the circles radius is 2, then you have to square 3 which is 9. to square a number you have to take that number and multiply it by itself , in this case i did 3x3 to get the radius squared. OK, so now that i have the radius squared you need to multiply it by pi. which is 3.14 , so 9 x 3.14 = 28.26 the formula is area = pi x radius squared.
Boundry of circle is called circumference.
