Answer:

1519.76cm² is your answer (area if the smaller circle)

Step-by-step explanation:

half of the work you have done the remaining you want to do is to find the radius of the smaller circle it's done by dividing the diameter of the smaller circle by 2 the diameter is 44 for the smaller circle and the radius us 22 substitute in the area formula of the circle pi x r² you will find the answer

but if you asked the dark shaded part the answer is not that it is 7636.48cm²

hope it was helpful

good morning

\large\bf\underline\green{Given:-}

AC = 54cm

BC = 10cm

➡ \: \pi_{1}Radius \:  \: larger \:  \: circle  \: OA=27cm \frac{54}{2}

=27cm

\large\bf\underline\red{</strong><strong>A</strong><strong>B</strong><strong>\</strong><strong>:</strong><strong>i</strong><strong>s</strong><strong>\</strong><strong>:</strong><strong>a</strong><strong>\</strong><strong>:</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>o</strong><strong>f</strong><strong>\</strong><strong>:</strong><strong>s</strong><strong>m</strong><strong>a</strong><strong>l</strong><strong>l</strong><strong>\</strong><strong>:</strong><strong>c</strong><strong>i</strong><strong>r</strong><strong>c</strong><strong>l</strong><strong>e</strong><strong>}

AB = AC - BC

⠀⠀ = 54 - 10

⠀⠀ = 44cm

 ➡Radius\:of\:small\:circle \: r_{2} =  \frac{d}{2}

 ⠀ ⠀ ⠀ ⠀ ⠀ =  \frac{44}{2} = 22cm

\large\bf\underline\red{Area\:of\:shaded \:reagion= Area\:of\:large\:circle- Area\:of\:small\: \:circle}

 =  {\pi}r_{1}^{2}  ⠀ ⠀ ⠀  ⠀ ⠀ ⠀⠀ ⠀ ⠀⠀=  - {\pi}r_{2}^{2}

 =  \frac{22}{7} \times 27 \times 27 ⠀ ⠀ ⠀ ⠀  =-  \frac{22}{7} \times 22 \times  \times22

 = 2291.14 ⠀ ⠀ ⠀ ⠀ ⠀ ⠀  ⠀=- 1521.14

 =  {770cm}^{2}
