Question

please show one example permieter in circle and area in circle​

Answer 1

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 4\ cm}\end{picture}$

Let the Radius be 4cm:

Perimeter:

2πr

2×22/7×4

=25.14

Area:

πr²

22/7×4²

=50.28

Kindly refer to the picture for diagrammatic view.

Answer 2

Perimeter = 2πr = 2 × 227 × 7 m = 44 m;Area = πr2 = 227 × 72 m2 = 154 m2. ⟹ r = 21 cm.
