Answer:
The total surface area of a cylinder is
.
Step-by-step explanation:
We have,
Height of a cylinder, h = 5 cm
Radius of a cylinder, r = 2 cm
It is required to find the total surface of a cylinder. The formula of the total surface area of cylinder is given by:
![A=2\pi r h+2\pi r^2\\\\A=2\pi r (r+h)\\\\A=2\pi \times 2 (2+5)\\\\A=28\pi \ cm^2](https://tex.z-dn.net/?f=A%3D2%5Cpi%20r%20h%2B2%5Cpi%20r%5E2%5C%5C%5C%5CA%3D2%5Cpi%20r%20%28r%2Bh%29%5C%5C%5C%5CA%3D2%5Cpi%20%5Ctimes%202%20%282%2B5%29%5C%5C%5C%5CA%3D28%5Cpi%20%5C%20cm%5E2)
So, the total surface area of a cylinder is
. Hence, the correct option is (A).
