You included the area of the circular base.
I understood that "lateral surface area" excluded the base of the solid.
For the volume I got pi(6^2)(8)/3 = 301.5929
mmmmh, now would that be a coincidence that this answer is the same as the one you got for the total surface area???
Are these correct
2a) For the cone, find the Lateral Surface Area in square inches. (Hint: Use the pythagorean theorem to find the slant height)
diameter= 12 inches, height= 8 inches
Lateral Surface Area= 301.5928 square inches
2b) Find the volume in cubic inches
Volume = 88.49555 cubic inches

so its the same???
no, just a simple coincidence with those numbers.
I tried it with a cone of height 12 and radius 5, resulting in a slant height of 13
the total surface area would be 65pi + 25pi = 90pi and
the volume would be 25pi(12)/3 = 100pi
All we need in one exception to our perceived relationship and it is pooched.
