Question 935230
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*r*h}}}
If the floor is included, it's pi*r^2
---
For the cone:
{{{Area = pi*r*s}}}
s = slant height
{{{s = sqrt(18^2 + 3.3^2)}}}
