Question

how to learn formula of area related to circle class 10​

Answer 1

Step-by-step explanation:

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

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

3. Area of a circle = πr2

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

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

Answer 2

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
