Answer:
46.37 square units
Step-by-step explanation:
If the right triangle is revolved the figure shown about the y-axis completely, the figure will be formed as a cone. As you can see in my attached photo.
So, the radius of the cone is : 2 units
the slant height is: = (use pytagon theory)
Hence, the total surface area of the resulting figure
SA = π * the radius * the slant height + π*
= 3.14*2* + 3.14*2*2
= 33.81 + 12.56
=46.37 square units
