meaning of circle
At the point when the arrangement of the multitude of focuses situated at a specific separation from a specific point are joined, then the mathematical figure got is known as a circle.

Circle Properties – Terms Connected with Circles
center
The decent point in the circle is known as the middle.
In this way, the arrangement of focuses is at a specific separation from the focal point of the circle.
Range
Range is the decent distance between the middle and the arrangement of focuses. It is signified by “R”.
Measurement
A width is a line portion that has the limit points of circles as endpoints and goes through the middle.
In this way, coherently a breadth can be broken into two sections:
a piece of a circle from a limit highlight the middle
What’s more, the second part from the middle to the subsequent limit point.
Consequently, measurement = two times the length of the range or “D = 2R”.
Periphery
It is the proportion of the external limit of the circle.
Thus the length of the circle or the perimeter of the circle is known as the outline.
boundary of a circle
curve of a circle
The curve of a circle is a piece of the periphery.
From Any Two-Focuses On The Limit Of The Circle, Two Curves Can Be Drawn: A Minor And A Significant Circular Segment.
Minor Circular Segment: The Short Curve Shaped By Two.
Significant Circular segment: A long curve shaped by two.
bend of a circle
Area of a circle:
An area is shaped by joining the end points of a curve with the middle.
Associating the endpoints with the middle, two districts will be gotten: minor and major.
Of course, we just consider the short region except if generally noted.
area of a circle
semi circle
The crescent is half of the circle or,
At the point when a circle is separated into halves a crescent is gotten.

Properties of lines all around
Wire
A harmony is a line fragment whose end point lies on the limit of the circle.

digression line
Digression is the line which contacts the circle anytime.
Properties Of Digression
The range is consistently opposite to the digression where it contacts the circle.

properties of points all around
stamped point
An engraved point is the point framed between two harmonies when they meet at the limit of a circle.

properties of engraved points
1. The points subtended by a similar circular segment on the perimeter of a circle are dependably equivalent. Properties of points engraved by a circular segment
2. The point in a half circle is dependably 90°. Properties of points engraved in the mid-point of a half circle
A focal point is the point when two line sections meet to such an extent that one of the line fragments is at the middle and the other is at the limit of the circle.
Properties of engraved points Focal point
mid point property
The point subtended by a circular segment at the middle is two times the point subtended by a similar bend.

Significant Circle Equations: Region and Border
Following are a few numerical equations that will assist you with working out the area and circuit of a circle.
Edge:
Edge or outline of circle = 2 × × R.
Length of the bend = (focal point subtended by the circular segment/360°) × 2 × × R.

Area of circle = × R²
Region of the area =(central point subtended by the area/360°) × × R².
Rundown of all properties of a circle
properties of circle
Here is a concise rundown of the multitude of properties we have advanced such a long ways in this article.
significant properties
Lines in a circle are dropped opposite to the focal point of the harmony what isolates the harmony into halves.
The digression range is generally opposite to the digression where it contacts the circle.
Points recorded in a circle 1. The points subtended by a similar bend on the outline of a circle are consistently equivalent.
2. The point in a crescent is consistently 90.
Focal point The point subtended by a bend at the middle is two times the point subtended by a similar curve.
Significant equation 2 × R × circuit of the circle.

Stage 1: Given
The length of the other different sides with the exception of the hypotenuse of a right calculated triangle are 6 cm and 8 cm.
This triangle is portrayed all around.
Stage 2: To find

Question 1 Circles
Applying the property that the point in the crescent is 90º, we can say that Stomach muscle is the width of the circle.
What’s more, when we find the length of the width, we can track down the range, and afterward we can track down the region of the circle.
On applying Pythagoras hypothesis to ABC,
AB² = AC² + BC
Stomach muscle = 10 cm
Since Stomach muscle is measurement, Abdominal muscle = 2R = 10
