if answer is correct I'll mark as brainliest answer.come on

Answer 1

Here is ur answer...

Hope it helps u☺

Answer 2

first draw the diagonal of the rectangle which is equal to the diameter of the circle so, BD or AC = diameter of circle

using pythagoras theorem in triangle ADB

$h^2=p^2+b^2$

$DB^2=12^2+5^2$

$DB=\sqrt{144+25}$

$DB=\sqrt{169}$

$DB=\sqrt{13^2}$

$DB=13$

as DB=d so, d=13 and r=13/2

now,

ar.of shaded region=ar. of circle-ar. of rectangle

                                =$\pi r^2-l*b$

                                =3.14*13/2*13/2-12*5

                                =132.73-60

                                =$72.72 cm^2$
