What is the total surface area of a right rectangular cylinder with a radius of  and a height that is 1.5 times its diameter?18 Mark For ReviewA) B) C) D)

The question seems to be incomplete as the radius of the cylinder is not provided. However, I can provide the formula to calculate the total surface area of a right rectangular cylinder (which is actually just a regular cylinder).

The total surface area of a cylinder is given by the formula:

2πr(h + r)

where:

• r is the radius of the base of the cylinder
• h is the height of the cylinder

In this case, the height is 1.5 times the diameter. Since the diameter of a circle is twice the radius (d = 2r), the height of the cylinder is 1.5 * 2r = 3r.

Substituting h = 3r into the formula, we get:

2πr(3r + r) = 2πr(4r) = 8πr²

So, the total surface area of the cylinder is 8πr². Once you have the radius, you can substitute it into this formula to get the total surface area.
