<h3>The perimeter of circle = 17.6 cm</h3><h3>Perimeter of square = 22.4 cm</h3>
Step-by-step explanation:
The total length of the wire = 40 cm
Let us assume the circumference of the circle = k cm
So, the circumference of the square = ( 40 - k) cm
Now,as circumference of circle = 2πR
⇒2πR = k cm or, R =
Area of the circle = πR²
or, A =
....... (1)
Similarly , perimeter of square = 4 x Side
⇒ 4 x Side = ( 40 - k) cm ⇒ S =
Area of the square = (Side)² =
Solving, we get: ....... (1)
So, combining (1) and (2), total area A is
or, we get: A = 0.07962 k² + 0.0625 k² + 100 - 5 k
A = 0.1422 k² - 5 k + 100
For axis of symmetry :
⇒ k = 17.6 inches
So, the perimeter of circle = 17.6 cm
Perimeter of square = (40 - 17.6 ) = 22.4 cm
If I've read this correctly, it looks like this.
If that is correct, then the first step is to put the top part of the denominator over 3x
The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.
