To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:
Then, square root both sides to get rid of the 'squared':
Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.
Step-by-step explanation:
all work is shown and pictured
Gradient of AB = y1-y2/x1-x2
= -3-0/1-1
= -3/0
gradient of AB = gradient of CD (as AB is parallel to CD)
therefore D = 3+y3/0+x3
= -3+2/0+4
= -1/4
since y/x of D = -1/4,
the coordinates of D is (4,-1) [option B]
