Find the area of the shade region. round to the nearest tenth

450.5 in²

Step-by-step explanation:

The area of the triangle

= (20×21)/2

= 210 in²

The hypotenuse of the triangle

=

=

=

= 29 in

The hypotenuse of the triangle (29 in)

= the diameter of the circle

The formula of area of a circle= πr²

The radius of the circle

= 29÷2

= 14.5 in

The area of the circle

= π × 14.5²

= 660.5 in² (rounded to the nearest tenth)

The area of the shaded region

= 660.5 - 210

= 450.5 in²
