Answer:

Area of the given quarter of the circle=78.5units^2

Step-by-step explanation:

The given figure is a quarter or sector of a circle with an angle of 90°

Area of the quarter of a circle:

                                              =    \frac{\pi *r^2}{4}

Area of the given quarter with a radius of 10 unit

                                 =\frac{3.14*10*10}{4}

                                =\frac{3.14*100}{4} \\\\=\frac{314}{4} \\\\=78.5units^2

The area of the given quarter of the circle=78.5units^2
