Answer:
128 square inches
Step-by-step explanation:
diagonal of the shaded region = length of the outer square = 16 in
Area of the shaded region =1/2*d²
![=\frac{1}{2}*16*16=8*16=128](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%2A16%2A16%3D8%2A16%3D128)
V= L*w*h
21.322.132= 3434*1212*h
h= 21.322.132/3.434* 1212 = 5.330.533/1.040.502
h ≈5,123 inch
We have a right triangle
one leg is 2.4 in
the other leg is 7.4/2=3.7 in (radius)
the hypotenuse is
c^2=a^2+b^2
c^2=5.76+13.69=19.45
c=sqrt 19.45=4.41 in
