Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.
Then that's your answer.
You are looking for the circumference. which is C(circumference)= 
x r (radius)
the radius is =to half of the diameter.
c=56.55
the radius is =to half of the diameter.
c=56.55
