To start, the question is asking for surface area of a cylinder, meaning you will have to use this formula to find it: A=2πrh+2πr^2.
Since you already know that the diameter of the plastic cylinder is 4 marbles long, and each marble is 2 cm in diameter, you would multiply 4 and 2 to get that your diameter is 8 cm. However, since the surface area of a cylinder formula uses radius, you would simply divide 8 by 2 to get that the radius of the cylinder is 4 cm.
Now, since you already know that the height of the cylinder is equal to 10 marbles, multiply the amount of marbles by 2 to get that the height of the cylinder is 20 cm.
Now that you know the height and the diameter of the cylinder, plug the values into the formula: A=2π(4)(20)+2π(4)^2.
Assuming that pi is 3.14, simplify the equation as according to PEMDAS and you get that the area of plastic needed to make one cylinder is 602.88 cm squared

Answer:
Step-by-step explanation:
The number of miles is directly proportional to the amount of gas, then:
Where the amount can be modelled as the product of the maximum amount of gas and the percentage of occupied capacity. Hence:
Answer:
7416.8
Step-by-step explanation:
5,840 x 127%
Since she's 73 percent of the way there, we need to add the last 27 percent as well as put a one in front so it will work.
127%
Because this is not just 7416 steps you should consider rounding it if your teacher asks you to.
