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
