Anjali took a wire of length 88 cm and bent it into the shape of a
circle. Find the area enclosed by that circle. If the same wire is bent in the shape of a
square, then find the area enclosed by that square. Which shape encloses more area and
by how much? Take pie = 22

Step-by-step explanation:
length of wire=perimeter of circle=88 cm
2πr=88
=> 2*22/7*r=88
=> 44r=7*88
=> r=7*88/44
=> r=14cm
area of circle =πr^2
=> 22/7*(14)^2
=> 22/7*14*14
=>22*2*14
=> 616 cm^2
length of wire=permeter of square=88 cm
=>4*side =88 cm
=> side =88/4
=> side= 22 cm
side of square=22cm
area of square =(22)^2
=> 22*22
=> 484 cm^2
hence,area of circle is (616-484)=132 cm^2 more than area of square.
