Question

Find the surface are of the cylinder Plz explain

Answer 1

Answer:

Option D. 274.75 units²

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 3.5 units

Height (h) = 9 units

Surface Area (SA) =?

The surface area of the cylinder can be obtained as follow:

SA = 2πr (h + r)

NOTE: Pi(π) = 3.14

SA = 2 × 3.14 × 3.5 × (9 + 3.5)

SA = 21.98 × 12.5

SA = 274.75 units²

Thus, the surface area of the cylinder is 274.75 units²
