Question

Calculate the length of the circumference inscribed in the ABCD trapezium using the data shown in the figure

i need help :(​

Answer 1

Steps:

From the given figure,

Subtracting AB and DC, so,

`6 - 3 = 3 \: cm`

As we know that :-

`d = \sqrt{ {5}^(2) - {3}^(2) }`

`→d = 4 π cm`

Since:-

`c = πd`

`c = 4πd`

So, Answer is 4 π d
