Nothing shows up.. could you type it out?
Answer:The surface area would be 1809.56units
Step-by-step explanation:
Let's suppose we want to solve

with

. Separating variables and integrating, we get

Leaving the solution in this form, the initial condition gives

This means the solution is

.
Now if we were to write

, then we would have found

so that the solution would have been

.
But these two solutions are the same, since

. So we get the same solution regardless of where we place

, despite getting different values for

.
Z/3+10=-7/10
multiply both sides
10z + 300 = -21
move the constant to the right
10z= -21 - 300
Calculate
10z = -321
divide both sides ^^
answer : z=-321/10
