Question

how do I write equation for circle with diameter having endpoints (-3,4) and (5,-2)

Answer 1

Find midpoint of the diameter with these two given points first..

Answer 2

and once I find the midpoint how do I find radius?

Answer 3

\[Midpoint (x,y) = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\]

Answer 4

is the midpoint (1,1)

Answer 5

distance formula for radius

Answer 6

For Radius, first find the distance..

Answer 7

radius 5??

Answer 8

That will given you the diameter length, for radius, divide the distance by 2..

Answer 9

Yeah you are pretty much right.. :)

Answer 10

what do you mean pretty much. that doesn't count in math

Answer 11

Centrre (1,1) and Radius = 5..

Now use Standard Equation of Circle to write equation..

Answer 12

(x-1)^2 +(y-1)^2=25

Answer 13

Great... :)

Answer 14

thanks
