So today in math....
i learned.....
that the circumference of a circle is C=pie(d)
in a circle, the ratio of the length of a given arc to the circumference is equal to the ratio of the measure of the arc to 360
the area of a circle with radius r is given by the formula
the ratio of the area A of a sector of a circle to the area of the circle is equal to the ratio of the measure of the intercepted arc to 360
ya it all letters to me
