The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches. So, we can substitute 3 in for 'r' and 3.14 in for Then, we can simply multiply. Therefore, the circumference of the circle is 18.84 Next, we'll find the circle's area. Again, we can substitute 3 in for 'r' and 3.14 in for The, we'll square three and multiply. Therefore, the circumference is 18.84 and the area is 28.26.
