Answer:
P = 2l + 6m
Step-by-step explanation:

check the picture below.
the line QS is just a flat-line and therefore it has 180° on either side, so the angle QPR is 57°, as you see there, and since we know the diameter is 20, that simply means the radius of the circle is 10.

Answer:
The mid-point of AB is (5,6)
Step-by-step explanation:
The mid-point of two points lies between the middle of two points or divides the line in two equal parts.
The formula for finding mid-point, M, is:

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.
Given
(2, 3) and (8,9)
Putting the values in the formula

Hence,
The mid-point of AB is (5,6)
