Write an equation for a circle with center at (2,3) and radius of 6
(x-2)^2+(y-3)^2=36
Equation of circle is given by: \[(x-h)^2 + (y-k)^2 = r^2\] Where, (h,k) = center and r = radius..
thnks u guys
So according to this: \[(x-2)^2 + (y-3)^2 = 6^2\] \[(x-2)^2 + (y-3)^2 = 36\]
Welcome dear..
thnk u i had to use an example so i wud kno how to do the rest so thnks
Write an equation for a circle with center at (-2,7) and diameter of 14. i got (x-2)^2+(y-7)^2=196 but they said it was wrong @waterineyes
@waterineyes ?
You are given with diameter.. firstly find the radius from it: 2*r = diameter 2*r = 14 r = 7 S0, on RHS 49 will come..
im lost so it ='s 49 not 196?
Yes you have to calculate radius first..
but i thought tht 14 wud be ^2?
No that is the diameter.. You have to half it when diameter is given..
but u didnt half 6
on the other problem
ohhhhhhh nevermind 6 was the radius
nd 14 is the diameter
yes..
lol im sorry i get it
it still says im wrong even with the 49???
