You can put this solution on YOUR website!
a tent in the form of a right circular cone is 5m high and its base is of radius 12cm
h = 500 cm, r = 12 cm
Gonna have to stand in that one.
-----------------
find
1-area of the canvas used to make the tent and
The area or the conical part is pi%2Ar%2Asqrt%28r%5E2+%2B+h%5E2%29
= pi%2A12%2Asqrt%28250000+%2B+144%29
=~ 18855 sq cm
The area of the floor is pi%2Ar%5E2
=~ 452 sq cm
---------------
2-volume of air space in it
V+=+pi%2Ar%5E2%2Ah%2F3
V = 144*500pi/3 = 24000pi cubic cm
v =~ 75398 cc
----------------
----------------
If the radius is actually 12 meters and not 12 cm, use this as an example and rework it.
