To start, you know that this question is asking for the surface area of one of the cylinders, and the formula to finding the surface area of a cylinder is A=2πrh+2<span>πr^2.
Now, to find the surface area, you first need to figure out the height of the plastic cylinder and its radius.
Since you know that the diameter (twice the radius) of the cylinder is equivalent to 4 marbles, and each marble has a diameter of 2 cm, the diameter of the cylinder would be 8 cm. Then, to find its radius, you divide by 2, so its radius is 4.
Now, since you know that the height of the cylinder is 10 marbles, you multiply 10 by 2 to get that the height is 20 cm tall.
Since you now have the values of the height and the radius, plug the values into the surface area of a cylinder formula (r is radius and h is height).
</span>A=2π(4)(20)+2π(4)^2.
<span>Assuming that pi is 3.14, when you simplify this using PEMDAS, you get
502.4+100.48 which then simplifies to 602.88, the area of the plastic to make one cylinder.

I’m not sure what the question is, so if you could tell me what the actual question is I might be able to answer it!
Answer:
20x+340
Step-by-step explanation:
20(x+17)
Using distributive property
(20×x)+(20×17)
20x+340

Based on the calculations, the volume of this pyramid is equal to: C. 324 cubic centimeters.
<h3>How to calculate the volume of a pyramid?</h3>
Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × base area × height
Next, we would determine the height of triangle ABC by using this formula:
Height = a × √3
Height = 6√3
Substituting the parameters into the formula for volume, we have;
Volume = 1/3 × 54√3 × 6√3
Volume = 1/3 × 972
Volume = 324 cm³.
