is zum
Find the cost of the convas required to make the tent if the cost of 1msaqure convas in rupies 70
​

Answer 1

Answer:

given,

height ( h) = 10m

base radius (r) = 24m

(1) slant hight = √{height ² + radius ²}

= √{10² + 24²} = 26m

(ii) surface area of canvas = surface area of cone = πr× slant hight

= 22/7 × 24 × 26 m²

total cost of canvas for making = surface area of canvas × rate

= 22/7 × 24 × 26 × 70

= 22 × 24 × 26 × 10

= 137280 ₹
