Evaluate the surface integral modifyingbelow integral from nothing to nothing integral from nothing to nothing with upper s f (x comma y comma z )ds using a parametric description of the surface. f (x comma y comma z )equalsx squared plus y squared, where s is the hemisphere x squared plus y squared plus z squared equals 36, for zgreater than or equals0 the value of the surface integral is nothing. (type an exact answers, using pi as needed.)

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
