Answer 2

Required Answer:-

Perimeter of the circle:-

$\longrightarrow$ $\underline{\boxed{\bf perimeter = 2πr}}$

here,

• ${\sf π}$ = $\sf\dfrac{22}{7}$ or 3.14
• r = radius of circle

Area of the circle:-

$\longrightarrow$ $\underline{\boxed{\bf Area = πr²}}$

here,

• ${\sf π}$ = $\sf\dfrac{22}{7}$ or 3.14
• r = radius of circle.
