Question

A wire of length 132cm is bent to form a rectangle of length 12 cm. The wire is rebent in a form of a circle. Which figure encloses more area.

Answer 1

Step-by-step explanation:

length of wire = perimeter of circle

132 = 2πr

132 = 2 x 22/7 x r

r = 21cm

now,

area orf circle = πr²

= 22/7 x 21 x 21

= 1386cm²
