Step-by-step explanation:
- Here, Height = 14 m
- Curved surface area = 352 sq. m
- So, we know that
- Curved surface area of cylinder = 2πrh
- 352 = 2*22/7*r*14
- 352 = 2*22*r*2
- Radius = 352/88 = 4 m
- Total Surface area of cylinder = 2πr(r+h) =2*22/7*4*(4+14) = 2*22/7*4*18 = 44/7*72 =452.6 m^2 (approx)
