The volume of the shape
We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.
External radius = internal radius + thickness
![\begin{gathered} \text{External radius = 4ft + 1ft } \\ =\text{ 5ft} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BExternal%20radius%20%3D%204ft%20%2B%201ft%20%7D%20%5C%5C%20%3D%5Ctext%7B%20%205ft%7D%20%5Cend%7Bgathered%7D)
Internal radius = 4ft (given)
Recall that the volume(V) of a full cylinder is:
![V\text{ = }\pi r^2h](https://tex.z-dn.net/?f=V%5Ctext%7B%20%3D%20%7D%5Cpi%20r%5E2h)
Since the cylinder is cut into two, the volume(V) is:
![V\text{ = }\frac{\pi r^2h}{2}](https://tex.z-dn.net/?f=V%5Ctext%7B%20%3D%20%7D%5Cfrac%7B%5Cpi%20r%5E2h%7D%7B2%7D)
height (h) = 12ft (given)

Answer:
IBi0
Step-by-step explanation:
We look at the child's genotype (lAi0).
We know that the blood type's genotype has 2 genes, one from the mother and one from the father.
If the genotype is lAi0 and one gene is, let's say, from mother (lA), we know exactly that the other gene is from father (i0).
So, father's genotype is lBi0 (a).
