\dfrac{\tan x-1}{\tan x+1}=\dfrac{\frac{\sin x}{\cos x}-1}{\frac{\sin x}{\cos x}+1}=\dfrac{\sin x-\cos x}{\sin x+\cos x}=\dfrac{1-\frac{\cos x}{\sin x}}{1+\frac{\cos x}{\sin x}}=\dfrac{1-\cot x}{1+\cot x}

Area of a circle is 80 cm². Work out the circumference of the circle.
GuDViN [60]

Answer:

The circumference of circle is: 31.714 cm

Step-by-step explanation:

Let C be the circumference of the circle

And A be the area of circle

It is given that:

A = 80cm^2

We have to find the radius first so that it can be used to find the circumference

The area of circle is given by the formula:

A = \pi r^2

Putting the value of area

80 = 3.14 * r^2\\\frac{80}{3.14} = r^2\\r^2 = 25.477

Taking square root on both sides

\sqrt{r^2} = \sqrt{25.477..}\\r = 5.0475\ cm

Now

C = 2\pi r

Putting the value of radius

C = 2 * 3.14 * 5.05\\C = 31.714\ cm

Hence,

The circumference of circle is: 31.714 cm
