A piece of wire is bent to form a square of area 121cm.
Calculate:
a)the length of each side of the square.
b)the perimeter of the square.
The piece of wire is now bent to form a circle using π=3.14
Calculate:
a)the radius of the circle
b)the area of the circle

well, 121 = 11^2
Yes i know that part but the part that's say the same wire is bent into a circle that's the part i don't get
c'mon, guy, think. Clearly the length of the wire is 44 cm.
So, for a circle to have a circumference of 44 cm, you need a radius given by
2πr = 44
r = 22/π
And the area would be
πr^2 = π(22/π)^2 = 484/π
So, for a circle to have a circumference of 44 cm, you need a radius given by
2πr = 44
r = 22/π
And the area would be
πr^2 = π(22/π)^2 = 484/π
How did you get the radius
u wont get the radius simply, fr dat u have find it out
length of the wire = c of circle
44 cm = 2 pi r
r = 44 by 2 * pi
r = 22 / pi
44 cm = 2 pi r
r = 44 by 2 * pi
r = 22 / pi
the answer is not clear to understand
