Question

how do I solve x^2+y^2=5,625 and graph?

I know this is an equation for a circle with R=75.

Answer 1

Well, you don't really solve it, you know the radius, so since there is no h or k, center is (0,0), so draw a circle around (0,0) with radius 75.

Answer 2

how do I know how far out from orgin to draw the circle?

Answer 3

What does radius mean?

Answer 4

point from center to edge

Answer 5

Exactly, so if the radius is 75, you know how far to go.

Answer 6

so just take the radius =75 and that is it

Answer 7

75 what? 75 squares on the graph paper

Answer 8

may be but it will be quite far ;)

Answer 9

are my points (0,75), (75,0), (0,-75) (-75,0)

Answer 10

Yup, you got it!

Answer 11

thanks

Answer 12

yes ur points are correct
