2)Calculate the surface area of a regular triangular pyramid with the base edges of length 12 and a slant height of 12. (Hint: Remember that the base of a regular triangular pyramid must be an equilateral triangle, not necessarily congruent to the sides of the pyramid.)

1)Approximate the volume of the regular triangular pyramid in problem 12 if the height is approximately 11.5

Okay the answer to the first problem about the sheet metal needed to cove this cylinder is 296.880, this number is the surface area of the cylinder.

anonymous · Answer

The unit on that would likely be m(meters)

anonymous · Answer

Now the volume that this cylinder should be given by v=pi*r^2h, so the answer should be 384.845
