Question

a circle with a radius of 5 units and center at P(6, 1)?

Answer 1

What are you supposed to do? Write the equation?

Answer 2

Which point lies on a circle with a radius of 5 units and center at P(6, 1)?

Q(1, 11)

R(2, 4)

S(4, -4)

T(9, -2)

Answer 3

check the distance between a point and the center

Answer 4

pick the one that equals 5

Answer 5

You could do the distance formula

Answer 6

How Do You Do That ?

Answer 7

Another way to do it is to write the equation and test the value of x and y for eachone

Answer 8

the distance between \((x_0,y_0\) and \((x_1,y_1)\) is given by \(D=\sqrt{(x_0-x_1)^2+(y_0-y_1)^2}\)

Answer 9

thats the same thing @Venny

Answer 10

notice if we square both sides we have an equation of a circle:)

Answer 11

Yeah that way seems easier to me

Answer 12

they are the exact same way:)

Answer 13

thank you

Answer 14

@tomitrahicks did you get r?

Answer 15

yes
