Question

Write the equation for a circle that satisfies the given conditions.
1. Center (-4,-2) and the radius 14 units.
2.Center (5,-4) and the radius is 4 units.
3. Center (-8,7) and radius 1/2
4.Write an equation for the circle that satisfies the given set of conditions endpoints of a diameter at (11,18) and (-13,-19)

4.Write an equation for the circle the satisfies the given set of conditions.
Center (8,-9) and passes through (21,22)
5.Write an equation for the circle the satisfies the given set of conditions. Center (4,-7) and the radius 5 units.

Answer 1

the equation of a circle with center \((a,b)\) and radius \(r\) is given by \((x-a)^2+(y-b)^2=r^2\)

Answer 2

i know its a lot and i am sorry!!

Answer 3

if you are given center \((a,b)\) and a point it passes through \((c,d)\) then use the distance formula \(D=r=\sqrt{(a-c)^2+(b-d)^2}\) to get the radius and then use the equation above.

Answer 4

use this eq..

(x-a)^2+(y-b)^2=r^2

here (a,b) are oordinates of point given and r is radius..

Answer 5

Can yall please give me the answers, I have to get pass this test or my mom is going to strangle me. not really,but close. lol

Answer 6

read the rules, we are not here to take your test for u.

Answer 7
