Can soemone help meee i give brainlistt

Answer 1

First you find the area of the half circle cut out. area of circle is pi*radius² ; therefore the area of half of the circle is that equation divided by two. you get around 39 for the area of the half circle or 25pi/2. then find the area of the triange which is 1/2(base)(height) or 1/2(18)(20)=180

then do 180-(25pi/2) which equals to about 140.73009

Answer 2

Answer:

140.74

Step-by-step explanation:

1.area of right triangle

1/2*b*h=1/2*20*18=180

2.area of semi circle

1/2*pi*r^2=1/2*pi*5^2=39.26

r= d/2

180-39.26=140.74
