What is the formula for finding circle?

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

How will you solve problems involving circles?

How do you solve problems involving circles

What is circle with figure?

A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its centre.

What will be area of the circle?

The formula for the area of a circle is A = πr2, where r is the radius of the circle. The unit of area is the square unit, for example, m2, cm2, in2, etc. Area of Circle = πr2 or πd2/4 in square units, where (Pi) π = 22/7 or 3.14. A circle is a two-dimensional shape, it does not have volume.

How do you do the circle theorem?

Now for the theorems:

The angle at the centre is twice the angle at the circumference.
The angle in a semicircle is a right angle.
Angles in the same segment are equal.
Opposite angles in a cyclic quadrilateral sum to 180°
The angle between the chord and the tangent is equal to the angle in the alternate segment.

What are the 5 properties of a circle?

Circle Properties

The circles are said to be congruent if they have equal radii.
The diameter of a circle is the longest chord of a circle.
Equal chords of a circle subtend equal angles at the centre.
The radius drawn perpendicular to the chord bisects the chord.
Circles having different radius are similar.

What is the importance of circle?

Circles are still symbolically important today -they are often used to symbolize harmony and unity. For instance, take a look at the Olympic symbol. It has five interlocking rings of different colours, which represent the five major continents of the world united together in a spirit of healthy competition.
