3y -12 +3=9
3y -9 = 9
3y = 9+9
3y=18
y=18÷3
∴y=6

Explanation:
The formula for the surface area of a cylinder is

We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.
So that's how we get to

Answer:
6
Step-by-step explanation:
10x6=60-2=58
Answer:
625
Step-by-step explanation:
1. parenthesis first, so it simplifies to ((6+(8)2÷4*1)/2)^4
2. pemdas says that multiplication and division go before addition and subtraction, so ((6+(8)2÷4*1)/2)^4 becomes ((6+16÷4*1)/2)^4 ---> ((6+4)/2)^4
3. then simplify inside of the parenthesis, so it becomes 5^4, which is 625
