A tent of height 77dm is in the form of a right circular cylinder of diameter 36m and height 44 dm surmounted by a right circular cone. find the cost of the canvas at rs 3.50 per sq meter.
===========
77 dm = 7.7 meters
44 dm = 4.4 meters.
---
For the cylinder:
Area+=+2pi%2Ar%2Ah
If the floor is included, it's pi*r^2
---
For the cone:
Area+=+pi%2Ar%2As
s = slant height
s+=+sqrt%2818%5E2+%2B+3.3%5E2%29
