Question

Write an equation for a circle with center at (-2,7) and diameter of 14

Answer 1

(h, k) ---> (-2, 7)
D = 14
D = 2r

2r = 14
r = 7

(x - h)^2 + (y - k)^2 = r^2

Plug in all values given.

(x + 2)^2 + (y - 7)^2 = 49

Answer 2

(X+2)^2 + (Y-7)^2 = 7^2

As genral equation of circle is (x-h)^2 + (Y-k)^2=r^2
where h cuts on x axis
k cuts on y axis
and r is radius= (diameter/2)

Answer 3

wait so whats the answer 2?

Answer 4

(X+2)^2 + (Y-7)^2 = 7^2

Answer 5

oo alright sorry thanks

Answer 6

or
(X+2)^2 + (Y-7)^2 = 49

Answer 7

No problem

Answer 8

sorry my thing online said both were wrong
;(

Answer 9

not possible

Answer 10

\[\left( x+2 \right)^{2}+(y-7)^{2}=49\]

Answer 11

^^ Like I said too, what @reshabhraj just said should be the correct answer.

Answer 12

now it said its right...sorry guys my online class is dumb sometimes
now it accepted it though thank yall
