Question

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

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
