around the building. Find the cost of painting the curved surface area of all the pillars at
the rate of 35.50 per 1 m²​

Answer 1

Step-by-step explanation:

C.S.A of cone= pie×r×l

r=0.28m h=35m

l=root(r^2+h^2)

l=root(0.0784+1225)=35m

C.s.a. of 16 pillar = 22/7×0.28m×35m×16=492.8m^2

cost of painting pillar= 492.8×35.5=17494.4rupee

IF the cost in paise convert 17494.4 into rupee is 174.944 rupee
