The circumference of the smaller circle is 20% of the circumference of the larger circle. Find the circumference of the larger circle. Round your answer to the nearest tenth. The smaller circle is 6 inches in diameter.
circumference of smaller circle = 2*pi*r = 2*pi*3 = 6pi so circumference of larger circle = 6pi / 0.2 = 30 pi units = 94.2 inches to nearest 10th inch.
