Question

30800 cm^3 water can be filled in cylindrical vessel if its internal radius is 14 cm then find its internal curved surface area

plsss solve its urgent help me guys​

Answer 1

Given:

Volume of Cylindrical Vessel = 30800cm³

Internal radius = 14cm

We know that, Volume of a cylinder = πr²h

According to the question,

πr²h = 30800

22/7 × 14 × 14 × h = 30800

22×2×14×h = 30800

h = 30800/616

Therefore, h = 50cm

Inner Curved surface area = 2πrh

C.S.A = 22/7 × 2 × 14 × 50

C.S.A = 22 × 2 × 2 × 50

C.S.A = 88 × 50

Therefore, C.S.A of the Cylindrical Vessel is 4400 cm²
