Answer:-

Area of circle is given by ,

$\large{\underline{\boxed{\red{\tt{\dag \:\:Area_{circle}\:\:=\:\:\pi r^2 }}}}}$

$\large{\underline{\boxed{\red{\tt{\dag \:\: Circumference_{circle}\:\:=\:\:2\pi r }}}}}$

• A circle may also be defined as a special kind of ellipse in which the two foci are coincident and the eccentricity is 0.
• A circle has infinite number of Diameters.
• Two circles cannot have more than two points in common.
• Diameter of a circle is double of radius.
• Diameter is the largest chord of the circle.
• A line which touches the circle at only one point is called tangent .
• A line which cuts circle at more than one point is called is secant .
• Two circles with same centre are called concentric circles.
