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

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

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

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

the answer is not clear to understand

A piece of wire is bent to form a square of area 121 calculate

To solve this problem, let's break it down step by step.

a) Calculating the length of each side of the square:

The area of a square can be found by squaring the length of one side. So, let's denote the length of each side of the square as "s."

Given that the area of the square is 121 cm², we can set up the following equation:

s² = 121

To find the length of each side, we need to find the square root of both sides of the equation:

√(s²) = √(121)

Simplifying this, we get:

s = 11 cm

Therefore, the length of each side of the square is 11 cm.

b) Calculating the perimeter of the square:

The perimeter of a square can be calculated by multiplying the length of one side by 4:

Perimeter = 4s

Plugging in the value of s, we get:

Perimeter = 4 * 11 = 44 cm

Therefore, the perimeter of the square is 44 cm.

Now, let's move on to the circle.

a) Calculating the radius of the circle:

In a circle, the radius is the distance from the center of the circle to any point on the circumference. Since the wire is bent to form a circle, the length of the wire will be equal to the circumference of the circle.

Circumference = 2πr

Given that π = 3.14, we can substitute this value into the equation:

Length of the wire = 2 * 3.14 * r

Given that the length of the wire is equal to the perimeter of the square (which is 44 cm), we can set up the following equation:

44 = 2 * 3.14 * r

Simplifying this equation, we get:

r = 44 / (2 * 3.14)

r ≈ 7.006 cm

Therefore, the radius of the circle is approximately 7.006 cm.

b) Calculating the area of the circle:

The area of a circle can be calculated using the formula:

Area = πr²

Given that π = 3.14 and we have already calculated the value of r as approximately 7.006 cm, we can plug these values into the equation to find the area:

Area = 3.14 * (7.006)²

Area ≈ 153.938 cm²

Therefore, the area of the circle is approximately 153.938 cm².
