C 6764
You need to find the total surface area which is 21249.73271
Then times each option (a,b,c,d) by pi to see if you get 21249.7321

Answer:

[tex]6764\pi[/tex]

Step-by-step explanation:

3876[tex]\pi[/tex]

Step-by-step explanation:

The Surface area of the Cylinder is given by the formula

[tex]SA=2\pi r^2+2\pi rh[/tex]

Here we are given with the value of radius and the height as 38 mm and 51 mm.  

Now we put the values of r and h in the above formula and evaluate he Surface Area

[tex]SA= 2\pi*38^{2}+2\pi*38*51\\SA=2888\pi+2\pi*1938\\SA=2888\pi+3876\pi\\6764\pi[/tex]

Hence the Surface area is

[tex]SA=6764\pi[/tex]
