Circumference is 2*pi*r
2 * 3.142 * 11.2 = 70.3808, to 1 decimal place is 70.4cm^2
Answer:
Perimeter = 44cm
we know that square has 4 sides which are same
so perimeter means sum of all 4 sides
4 × s = 44cm
s = 11cm
Each side will be of 11cm.
Now area of square is Square of its side length.
so area = 11 × 11 = 121 cm^2
The volume is 214*8*2012
=3,444,544
