Answer:

The area of the shaded portion is 450.185 in^2

Explanation:

21^2+20^2=841

The square root of 841 is 29

29+20+21=70

70*1/2=35

35-29=6

35-21=14

35-20=15

The square root of 35*6*14*14=210

The area of the triangle is 210 in^2

The diameter of the circle is 29, so the radius is 14.5

14.25^2=210.25

210.25*3.14=660.185

660.185-210=450.185
