Answer:
[tex]\boxed{\sf \frac{15}{22} }[/tex]
Step-by-step explanation:
The radius of the circle is 7 cm.
The two legs of the triangles are 7cm as well.
Area of a trinagle is ( base × height )/2.
[tex]\frac{7 \times 7}{2} =24.5[/tex]
Multiply the value by 2 since there are two triangles.
[tex]24.5 \times 2 = 49[/tex]
Calculate the area of the circle.
[tex]\pi r^2[/tex]
The radius is given.
[tex]\pi (7)^2[/tex]
Take [tex]\pi[/tex] as [tex]\frac{22}{7}[/tex]
[tex]49(\frac{22}{7} )[/tex]
[tex]=154[/tex]
Subtract the area of the two triangles from the area of the whole circle.
[tex]154-49=105[/tex]
The area of the shaded part is 105 cm². The total area of the shape is 154cm².
[tex]\frac{105}{154} =\frac{15}{22}[/tex]
