Answer:
77 in ^2 is the best estimate
Step-by-step explanation:
We can get the total area from the sum of the triangle and the semi circle
semicircle
1/2 the area of the semicircle
A = 1/2 pi r^2
1/2 (3.14) ( 4^2)
25.12
Now find the area of the triangle
The base is 16 -r = 16-4 = 12
The height is 8
A = 1/2 bh
= 1/2 (8) (12)
= 48
The total area is 25.12+48 =73.12
