Final answer:
To find PR, we can use the fact that the ratio of the distances is the same as the ratio of the coordinates in the polar coordinate system. Using the given ratio and the distance OR, we can solve for the distance PR.
Step-by-step explanation:
In this problem, we are given the ratio of the distances OP: PQ: QR as 3:6:2. We are also given that the distance OR is 22 units. We need to find the distance PR. To find PR, we can use the fact that the ratio of the distances is the same as the ratio of the coordinates in the polar coordinate system.
Let's denote the distance OP as x. Since the ratio of OP:PQ:QR is 3:6:2, we can write:
OP = 3x, PQ = 6x, QR = 2x
Since OR = OP + PQ + QR, we can substitute the values to get:
22 = 3x + 6x + 2x
Simplifying the equation, we get:
22 = 11x
Dividing both sides by 11, we find that x = 2.
Therefore, the distance PR is PQ + QR = 6x + 2x = 8x = 8 * 2 = 16 units.
