How do I calculate the area of a circle?
The area of a circle is pi times the radius squared (A = π r²).
How do you find the equation of a circle given two points and a line?
Use the Distance Formula to find the equation of the circle. Substitute (x1,y1)=(h,k),(x2,y2)=(x,y) and d=r . Square each side. The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .
What does the equation of a circle mean?
The equation of a circle is a way to express the definition of a circle on the coordinate plane. If the center of the circle is at the origin of the coordinate plane, the equation is where r is the radius. When the center of the circle is at the point (h,k), the equation becomes .
How do you find the equation of a line?
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
How do you find the radius of a circle with the center?
The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.
