Answer: The surface area of right cylinder is \(198\pi \text{ units}^2\)
Step-by-step explanation:
To calculate the total surface area of cylinder, we use the formula:
\(\text{Total surface area of cylinder}=2\pi r(r+h)\)
where,
r = radius of cylinder = 9 units
h = height of the cylinder = 2 units
Putting values in above equation, we get:
\(\text{Total surface area of cylinder}=2\pi \times 9(9+2)\\\\\text{Total surface area of cylinder}=2\pi \times 9\times 11\\\\\text{Total surface area of cylinder}=198\pi \text{ units}^2\)
Hence, the surface area of right cylinder is \(198\pi \text{ units}^2\)
