Hoi!
The converse of the Pythagorean Theorem states that <span>if the square of the length of the longest
side of a triangle is equal to the sum of the squares of the other two
sides, then the triangle is right.
To determine if this is a right triangle, let's figure out the values of each side.
√36 = 6
√18 = 4.2
Now we use the formula a² + b² = c² to determine if this is a right triangle.
4.2² + 4.2² = 6²
18 + 18 = 36
36 = 36
This triangle is a right triangle, so your answer is True.

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
