Answer:

Step-by-step explanation:
Total Surface Area of cylinder = Lateral Surface Area + Area of both circle bases.
Lateral Surface Area = Circumference of Circle
Height
Lateral Surface Area = 
Area of one circle base: 
Area of both circle bases: 
Total Surface Area = 
You start with the top number of each fraction and multiply them. So 2x3=6. Next you take the bottom number and multiply. So 3x4=12. That would give you a fraction of 6/12. 6 is half of 12 so 6/12 simplified is equal to 1/2. Hope this helps!
8 because AB=BC as they are isosceles and 5/2.5=2 therefore ACx2=JL= 8
Answer:
1
Step-by-step explanation:
The amplitude is 1.
This graph does not go through the origin, but has been translated up by 1 unit. If you draw a horizontal line through y = 1 you will see that the maximum distance the curve reaches above y = 1 is 1, which is the amplitude.
