Answer:
67 in
Step-by-step explanation:
Because these are congruent figures, you know that the last remaining segment is 67in
Its D............................
<span>S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract </span><span>2Πr2 on both sides.
</span>S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = <span>2Πrh
</span>
Step 2 . divide <span>2Πr on both sides
</span>
(S - 2Πr2)/2Πr = 2Πrh/<span>2Πr
</span><span>h = </span>(S - 2Πr2)/2Πr
