Answer:
137280 ruppes
Step-by-step explanation:
total cloth req. = curved surface area of the tent
ie. A= Pai*r*l
L²= r² +h²
= (24)²+(10)²
= 576+100
=676
L=26 now area
= 22/7(24)(26)
= 1961.14
now req cost = area * 70
= 1961.14*70
=137280 rupees

Answer:
A = Πr( r + √(h^2 + r^2
= 22/7 × 24 (24 + √ (100 + 576)
= 22/7 × 24 (24 + √676)
= 22/7 × 24(24 + 26)
= 22/7 × 24 × 50
= 22 × 24 × 7.14
= 3769.92
cost = 3769.92 × 70
= Rs 263894.4
