Question 697629
awire of length 44cm is bent to a shape of circle.
 find the radius of circle and also its area.
find r using the circumference formula
2*{{{22/7}}}r = 44
{{{22/7}}}r = 22
r = 7 cm is the r
then find the are
A = {{{22/7}}}*{{{7^2}}}
A = 154 sq/cm is the area
:
 If the same wire is bent into the shape of a square what will be the length of each of its sides? 
which figure encloses more area, the circle or square(use pi= 22/7)
{{{44/4}}} = 11 cm is the side of a square with a perimeter of 44 cm
11^2 = 121 sq/cm is the area
