Given:

The diameter of the cylinder is 8 cm.

The radius of the cylinder is 4 cm.

The height of the cylinder is 18 cm.

We need to determine the surface area of the cylinder.

Surface area of the cylinder:

Let us determine the surface area of the cylinder.

The surface area of the cylinder can be determined using the formula,


SA=2 \pi r(r+h)

where r is the radius of the cylinder and h is the height of the cylinder.

Substituting r = 4 and h = 18 in the above formula, we get;


SA=2 \pi (4)(4+18)


SA=2 \pi (4)(22)


SA=176 \pi

Thus, the surface area of the cylinder is 176π cm²

Hence, Option d is the correct answer.
