Question

ans is
πa^2-2a^2
how?​

Answer 1

Answer:

area of shaded portion = area of circle -area of rectangle

$area \: of \: circle = \pi \: x \: {a}^{2}$

area of rectangle = 2( l * b )

by Pythagoras theorem

${a }^{2} = multiplication \: o fadjacent \: sides$

so area of rectangle =

$2 \times {a}^{2}$

so the ans is so

Answer 2

Step-by-step explanation:

Answer:

area of shaded portion = area of circle -area of rectangle

area \: of \: circle = \pi \: x \: {a}^{2}areaofcircle=πxa

2

area of rectangle = 2( l * b )

by Pythagoras theorem

\begin{gathered}{a }^{2} = multiplication \: o fadjacent \: sides \\\end{gathered}

a

2

=multiplicationofadjacentsides

so area of rectangle =

2 \times {a}^{2}2×a

2

so the ans is so
