# Calculate the superficial area

Given ?(u, v) = (u + v, u, v), 0 ? u ? 1, 0 ? v ? 1.

a) find the superficial area of ?
b) evaluate the integral ? ? xyzdS.

given S the part of the cone parameretized by
x = r cos(?), y = r sin(?), z = r, 3 ? r ? 5, 0 ? ? ? 2?

a)calculate the superficial area of ?
b) evaluate the integral ? ? xyzdS.

• The bounty seems too low

• I increased it now

• One question, what do you mean by Φ xyzdS ?

• Do you mean the integral of the function xyz over the surface? That's only thing that I can think of.

• yes
