A circle has its center at (3,-2). The radius of the cirlce extends to the point (3,2). What is the approximate circumference of the cicle?
+130536 The distance from the center to the point on the circle is the radius.....and we can find this using the distance formula......so we have
r = √ [ ( 3 - 3)^2 + ( -2 -2)^2 ] = √ [ 0^2 + (-4)^2 ] = √ 16 = 4
So....the circumference is given by 2 * pi * r = 2 * 3.14 * 4 = about 25.12 units
