A tent is in the shape of a cylinder surmounted by a cone. If the height and radius of the cylindrical part are 3m and 14m, and the slant height of the cone is 10m, find the area of canvas used.
A704 m²
B440 m²
C264 m²
D616 m²
✓ Correct Answer: A — 704 m²
Canvas area = CSA of cylinder + CSA of cone = 2πrh + πrl = 2*(22/7)*14*3 + (22/7)*14*10 = 264 + 440 = 704 m².
