Answer:the least common denominator is 10 because 5x2 is 10 and then 10x1 is 10 its the least for both of them
Step-by-step explanation:
<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
1000 g=1kg
to convert to kg
1kg/1000g=conversion factor
multiply
6900g times 1kg/1000g
grams cancel
6.9 kg
Question A is b and question B is d
Start by dividing both sides by 3. Then take the square root of both sides. Then subtract 3 from both sides and divide by 2.
