Answer:

  150.72 in²

Step-by-step explanation:

The radius of the cylinder is half its diameter, so is 2 inches. We can rearrange the formula to make it easier to use, then fill in the numbers and do the arithmetic.

  SA = 2πR(R +H) = 2(3.14)(2)(2+10) = 150.72 . . . . square inches

Jill will need 150.72 square inches of wrapping paper.
