Question

Pls help me with this​

Answer 1

`\boxed{\sf (15)/(22) }`

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.

`(7 * 7)/(2) =24.5`

Multiply the value by 2 since there are two triangles.

`24.5 * 2 = 49`

Calculate the area of the circle.

`\pi r^2`

The radius is given.

`\pi (7)^2`

Take
`\pi` as
`(22)/(7)`

`49((22)/(7) )`

`=154`

Subtract the area of the two triangles from the area of the whole circle.

`154-49=105`

The area of the shaded part is 105 cm². The total area of the shape is 154cm².

`(105)/(154) =(15)/(22)`
