Step-by-step explanation:
Given,
Height h=10m
Base radius r=24m
(i) Slant height =h2+r2=102+242=676=26m
(ii) Surface area of canvas = Surface area of cone =π×r× slant height
=722×24×26=713728m2
Total cost of canvas for making = Surface area of canvas × rate
=713728×70
Total cost of canvas for making tent =Rs.137280
