Each of the small circles in the figure has a radius of 3. The innermost circle is tangent to the six circles that surround it, and each of those circles is tangent to the large circle and to its small circle neighbors. What is the ratio of the area of the shaded region to the area of the unshaded regions? The area of the shaded region is 2pi.

10000

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
