Answer 5

ok

Answer 6

since they give you the diameter you need to divide the diameter by two to get the radius

Answer 7

ok

Answer 8

\[2\pi(3.5)(2)\] should be your equation

Answer 9

ill start with the rectangle; the top of the cake has an area of 6x9, since the sides are the same for opposite sides we only need 2 equations, 2x2x9 and 2x2x6

Answer 19

ok

Answer 20
