Question

The total surface area, in square units, of a cylinder with a radius of r units and a height of h units can be represented by the formula
SA = 2πr² + 2πrh.
The first term of the expression represents the total area of the 2 circular bases of the cylinder, and the second term represents the lateral area of the cylinder.
In a certain cylinder, the radius is related to the height as shown in the
expression 2πx² + 2x (x + 3).
Which of the following statements could be true? Select all that apply.
A)The lateral area of a cylinder can be represented by the expression 2πx².
B)The height of a cylinder is 3 times the length of its radius.
C)The radius of a cylinder is equal to x units, and the height of a cylinder is equal to x + 3 units.
D)The area of one of the bases of a cylinder can be represented by the expression πX²
E)The radius of a cylinder is 3 units less than its height.
