Answer:
Yes
Step-by-step explanation:
We can add 20 to both sides and get 120=4v. Divide both sides by 4 and find that 30=v. Therefore, Lance is correct.
Answer:
the answer is 8
Step-by-step explanation:
basically ya add the one of the -2 nd another -2 together which makes it 0 bc its - so its made a wholr number now nd wha you do now is just keep going up now as if theres no negatives there
The base of the cylinder has area πr² = 36π ≈ 113.10 (assuming the radius is 6, and not the diameter, that's not clear to me).
If you take the paper wrapped around the cilinder, it would be a rectangular piece of height 12 and length equal to the circumference of the cilinder, being 2πr = 12π, so the area would be 12*12π=144π ≈ 452.39.
So in total this is 452.39+113.10 ≈ 565.49, that's answer D.
