The surface area of a cylinder can be determined with this formula
sa = surface area of 2 circles + surface area of side
sa = (2 × π × r²) + (2 × π × r × t)
Find the value of r (radius)
r = 1/2 diameter
r = 1/2 × 14.2
r = 7.1 cm
Plug the numbers into the formula
sa = (2 × π × r²) + (2 × π × r × t)
sa = (2 × π × 7.1²) + (2 × π × 7.1 × 12.8)
sa = 100.82π + 181.76π
sa = 282.58π
sa = 282.58 (3.14)
sa = 887.3
The surface area is 887.3 cm². The answer is third option.

In order to know the equivalent expression of the given above, all we need to do is to simplify it. So, for the exponents, what we need to do is just subtract.
The final answer would be 3/2xy^3. So the answer is option C. Hope this is the answer that you are looking for.
