Question

formula of area related to circles class 10th ​

Answer 1

Step-by-step explanation:

The distance around the circle or the length of a circle is called its circumference or perimeter.

Circumference (perimeter) of a circle = πd or 2πr,

Area of a circle = πr2

Area of a semicircle = \frac { 1 }{ 2 } πr2

Area of quadrant = \frac { 1 }{ 4 } πr2

Answer 2

Answer:

Step-by-step explanation:

Heya !!

The formulas of the chapter "Areas Related to Circles" are as follows :-

⭐Circumference of a circle = 2πr

⭐Area of circle = πr²

⭐Length of an arc of a sector of a circle with radius r and angle with degree measure A is

A / 360 × 2πr or A / 180 × πr

⭐Area of a sector of a circle with radius r and angle with degrees measure A is

A / 360 × πr²

⭐Area of segment of a circle = Area of the corresponding sector – Area of the corresponding ∆
