Question

find the area of a circle whose radius is 10 centimetre​

Answer 1

Given,

Radius of a circle = 10cm

To Find:-

Area of a circle

Calculations:-

$a = \pi {r}^{2}$

Pie = 3.14

a = 3.14×100

a=314

Circle:-

• A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre.

• equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

• There is no number of edges and number of vertices

Answer 2

$\large{\tt{\underline{\green{Given:- }}}}$

Radius of the circle = 10cm.

$\large{\tt{\underline{\pink{To \: Find:- }}}}$

Area of the circle = ?

$\huge{\tt{\underline{\blue{Note\: it:- }}}}$

$\large{\tt{π = 3.14}}$

$\huge{\tt{\underline{\red{Calculations:- }}}}$

$\large\implies{\tt{A = πr^2}}$

$\large\implies{\tt{A = 3.14 × (10)^2}}$

$\large\implies{\tt{A = 3.14 × 100}}$

$\large\implies{\tt{A = 314 cm}}$
