............................it's easy help me ​

Answer 1

Answer:

Step-by-step explanation:

. We know in a rectangle on e angle is 90 degrees. So angle d=90

By Pythagoras theorem

Ac=5cm

Half of ac = radius =5/2

Shaded region =are of circle - ar of rectangle

= Pie r^2-l.b

=7.6428

Answer 2

Answer:

➡️Hey there³²

$\huge{\fbox{\fbox{\green{\mathfrak{Answer\:\::}}}}}$3.625

Step-by-step explanation:

• AREA of rec. ABCD = l × b = 4×3=12

➡️Angle of A rectangle = 90°

• Using Pythagoras theorem :

$\huge{\fbox{\</strong><strong>pink</strong><strong>{\mathfrak{</strong><strong>T</strong><strong>o</strong><strong>\</strong><strong>:</strong><strong>Find</strong><strong>}}}}$ the diameter of following circle = Diagonal of the inner rectangle.

So, AC²=AB²+BC²

➡️AC²=3²+4²

➡️AC²=9+16

➡️AC²=25

➡️AC=√25

= 5

$\huge{\fbox{\orange{\mathfrak{</strong><strong>D</strong><strong>i</strong><strong>a</strong><strong>m</strong><strong>e</strong><strong>t</strong><strong>e</strong><strong>r</strong><strong>\</strong><strong>:</strong><strong>=</strong><strong>\</strong><strong>:</strong><strong>5</strong><strong>}}}}$

So, radius= half the diameter

➡️2.5

Area of circle= πr²

Value of π = 3.14

3.14×(2.5)²=3.14×6.25=15.625

➡️15.625-12

➡️3.625

So, the area of shaded region is 3.625 cm.
