Answer:
₹367.5
Step-by-step explanation:
Slant height of the conical tomb = 25m
Base diameter of the conical tomb = 14m
Cost of white washing per 100m = ₹210
Cost of white wash per metre = 210 ÷ 100
= 2.1
Radius of Base of the conical tomb = 7m
Area from base to height = 25 × 7 = 175
Cost of white wash = 175 × 2.1
= 367.5
