PLEASE HELP 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 = 22 + 2trh.
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
212? + 2x (x+3)
Which of the following statements could be true?
The radius of a cylinder is equal to x units, and the height of a cylinder is equal to x + 3 units.
The area of one of the bases of a cylinder can be represented by the expression ?
The height of a cylinder is 3 times the length of its radius.
The radius of a cylinder is 3 units less than its height.
The lateral area of a cylinder can be represented by the expression 272?.
