Please help on my surface area ;-; <3 good luck I will give brainiest to the correct one

207 square cm

Step-by-step explanation:

the rectangle because it has more long sides then the triangle

Option B is correct.

Step-by-step explanation:

Diagram of given scenario shown below.

Given that,

Diameter of cylinder is .

Height of cylinder is .

So, Radius of cylinder is

Volume of cylinder =                    {where, , is the radius                                                  

                                                               of cylinder and is height of cylinder}

Substituting the values we get,

Volume of cylinder

Therefore, Required volume of Cylinder rounding it to the nearest tenth ≈ .

Hence, option B is correct.
