Question

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​

Answer 1

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.
