Question

a circle with Centre (3,0) with radius 7 then equation of circle is ??
​

Answer 1

Answer:

X^2 - 6x +y^2 - 40=0 is the equation of circle.

Step-by-step explanation:

Equation of circle when center and radius is given =>( x-x1)² +(y-y2)²= r²

Therefore, ( x-3)² +(y-0)²= 7²

=> X²+9-6x+y²= 49

=>X²-6x+y² -40=0

Please mark my answer as brainliest please ♥️

Answer 2

Answer:

x^2+y^2-6x=40

Step-by-step explanation:

(3, 0) is the centre and 7 is the radius

then the eqn is (x-3) ^2+(y-0) ^2=7^2
