Answer:
The answer is 14
Step-by-step explanation:
14x2=28
14x3=42 so the greatest common factor is 14
i believe the formula you need is; SA= n(3/10 ib) + 9b
Total surface area = 2 * circular base + circumference * height
= 2 * pi*(4)^2 + 8pi * 12
= 32pi + 96pi
= 128pi answer
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!
