Answers
Answer:
sorry your question is not clear
Step-by-step explanation:
to me.
Answer:
Center:(2,2)
The center of a circle is a point from which all points on a circle are the same distance.
Radius:5
The radius of a circle is the length of a line segment from its center to its perimeter.
The radius is typically denoted as "r" or "R".
Diameter:10
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Circumference or (or Permieter) = 2*π*R = 2*3.14*5 = 31.4159265358979
The circumference of a circle is the distance around it.
Area:78.5398163397448
Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.
Equation
Standard Form
The standard form for the equation oif a circle is
(x-a)2+(y-b)2=r2
And in our particular case:
(x-2)2+(y-2)2=52
(x-2)2+(y-2)2=25
General Form
The general form for the equation of a circle is
x2 + y2 + Ax + By + c = 0
We can get the general form by expanding the equation of the standard form
(x-a)2+(y-b)2=r2
(x-2)2+(y-2)2=52
(x-2)2+(y-2)2=25
x2-4x+4+y2-4y+4=25
x2+y2-4x-4y-17=0
