Answer:
i) 10178.76
ii) 226
Step-by-step explanation:
total surface area for cone is pi×radius^2+pi×radius×length
i)
1. to find length
length^2 = 9^2×12^2 (pythagoras theorem)
length^2 = 225
length = 15
2. find T.S.A
pi×12^2 + pi×12×15 = 1017.87602
3. find cost
T.S.A × cost of a square meter = 1017.87602 × 10
= 10178.76 (2 d.p.)
ii)
1. find base area
pi×12^2 = 452.3893421
2. find no. of people that can be accommodated
452.389421 ÷ 2 = 226 (nearest whole no.)
