Let P be point on the circumference on the circle. perpendiculars PA and PB are drawn to point A and B on two mutually perpendicular diameter . If AB=36cm , the diameter of the circle is:

Text Solution

Verified by Experts

With the given details, we can draw a diagram.
Please refer to video for the diagram.
From the diagram, we can see all angles of `OAPB` are `90^@`.
It means, `OAPB` is a rectangle.
So, diagonals of `OAPB` will be equal.
`:. OP = PB = 36cm`
`OP` is radius of circle.
