Write the equation of each of the circles whose center is at (-5 ,-8) and the radius of 3√3 units.​

Sagot :

Answer:

Ans. 25

Step-by-step explanation:

The equation of a circle in coordinate system is given by

(x-h)²+(y-k)²=r²

where (h,k) is the centre of the circle and r is the radius.

So by substituting the values,

(x-(-5))² + (y-(8)²= 3√3²

So, (x+5)² + (y-8)²= 89 is the equation of the circle.

You can expand it if you want, but the form given above is easier to remember and use.

Hope this helps
