Explanation:
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
