Answer:
Step-by-step explanation:
surface area of cylinder=2 πr²+2πrh
=2πr(r+h)
=2π×12(12+18)
=24π×30
=720π
≈2261.9 cm²
Answer:

step 2:divide 25 and 5 to solve or x
step 3: x equals 5
Step-by-step explanation:
Answer:
Hey there!
I see you have to right idea, the first step is to write the equation: 6x-15+2x-2+4x-7=180. We can simplify this to 12x-24=180
Solving for x, we get that x=17.
Let me know if this helps :)
