A tent is cylindrical to a height of 11 m and its upper part is
conical. The total height of the tent is 16 m and diameter
of its base is 24 m. If 10% of the cloth is used for folds and
stitching, find the cost of the cloth required to make this
tent at the rate of Rs. 12 per m2. (Ans: Rs. 17424)
Step-by-step explanation:
Cylinder:
Diameter =42 m ⇒ Radius (r)=21 m
Height (h)=21 m
C.S.A. Cylinder =2πrh square cm
=2× 7 = 22
×21×21 =2772m 2
Cone:
Radius (r)=21 m, Height (h)=28 ml= 4 + 2 +r
2 = 28 – 2 +21
2= 1225
=35 m
C.S.A. of cone =πrl square cm
= 722
×21×35=2310m²
Total surface area of circus tent
=2772+2310=5082m²
The cost of 1 square metre = Rs. 12.50
Total cost of canvas =5082×12.50= Rs. 63,525..
