Question

what is the formula of circle ​

Answer 1

Perimeter of circle:-

$2\pi \: r$

Area of Circle:-

$\pi \: r { }^{2}$

The Value of Pie=

$22 \div 7$

Diameter of Circle=

$diameter \div 2$

Answer 2

$\bigstar\ \underline{\pmb{\bf{ \blue{Question}}}}$

What is the Formula of Circle ?

Solution

Below has provided all the necessary formulas related to the Concept of Circle starting from the very Basic level .

$\cdot \rm \red{ Diameter \: of \: Circle = 2 × radius ( r )}$

$\cdot \rm \pink{ Circumference \: of \: Circle = 2 \pi r }$

$\cdot \blue{\rm Area \: of \: a \: Circle =\pi r²}$

$\cdot \purple{ \rm\pi = \dfrac{Circumference}{Diameter}}$

Equation of Circle

$\tt(x - h)^{2} + (y - k) ^{2} = {r}^{2}$

Note :-

1. r = Radius of Circle
2. d = Diameter of Circle
3. C = Circumference of Circle

☯︎ Remember that

$\rm\pi \: is \: a \: number \: with \:a \: fixed \: value \: equals \: to \: \frac{22}{7} or \: 3.14$
