Step 1.1.1

Factor $h$ out of $2 r h$ .

$V = L (r^{2} \arccos (1 - \frac{h}{r}) + (h - r) \sqrt{h (2 r) - h^{2}})$

Step 1.1.2

Factor $h$ out of $- h^{2}$ .

$V = L (r^{2} \arccos (1 - \frac{h}{r}) + (h - r) \sqrt{h (2 r) + h (- h)})$

Step 1.1.3

Factor $h$ out of $h (2 r) + h (- h)$ .

$V = L (r^{2} \arccos (1 - \frac{h}{r}) + (h - r) \sqrt{h (2 r - h)})$

Step 1.2

Apply the distributive property.

$V = L (r^{2} \arccos (1 - \frac{h}{r}) + h \sqrt{h (2 r - h)} - r \sqrt{h (2 r - h)})$

Step 2

Apply the distributive property.

$V = L (r^{2} \arccos (1 - \frac{h}{r})) + L (h \sqrt{h (2 r - h)}) + L (- r \sqrt{h (2 r - h)})$

Step 3

Rewrite using the commutative property of multiplication.

$V = L r^{2} \arccos (1 - \frac{h}{r}) + L h \sqrt{h (2 r - h)} - L r \sqrt{h (2 r - h)}$

Step 4

Reorder $1$ and $- \frac{h}{r}$ .

$V = L r^{2} \arccos (- \frac{h}{r} + 1) + L h \sqrt{h (2 r - h)} - L r \sqrt{h (2 r - h)}$

Step 5

Reorder $L$ and $r^{2}$ .

$V = r^{2} L \arccos (- \frac{h}{r} + 1) + L h \sqrt{h (2 r - h)} - L r \sqrt{h (2 r - h)}$

Step 6

Reorder $2 r$ and $- h$ .

$V = r^{2} L \arccos (- \frac{h}{r} + 1) + L h \sqrt{h (- h + 2 r)} - L r \sqrt{h (2 r - h)}$

Step 7

Reorder $L$ and $h$ .

$V = r^{2} L \arccos (- \frac{h}{r} + 1) + h L \sqrt{h (- h + 2 r)} - L r \sqrt{h (2 r - h)}$

Step 8

Reorder $2 r$ and $- h$ .

$V = r^{2} L \arccos (- \frac{h}{r} + 1) + h L \sqrt{h (- h + 2 r)} - L r \sqrt{h (- h + 2 r)}$

Step 9

Move $L$ .

$V = r^{2} L \arccos (- \frac{h}{r} + 1) + h L \sqrt{h (- h + 2 r)} - r L \sqrt{h (- h + 2 r)}$

Step 10

Move $r^{2} L \arccos (- \frac{h}{r} + 1)$ .

$V = h L \sqrt{h (- h + 2 r)} - r L \sqrt{h (- h + 2 r)} + r^{2} L \arccos (- \frac{h}{r} + 1)$
