Question

c.s.a of a cylinder is 1760m sq base radius is 14 cm find the height of the cylinder

Answer 1

2πrh=1760
2×22/7×14/100×h=1760
88/100h=1760
h=2000 m

Answer 2

we know that curved surface area of cylinder is 2πrh

given,

csa of cylinder is 1760 m²

radius =14cm

1m²=100cm²

so,1760 m²=1760×100×100 cm²

                  =176000000cm²

2×22/7×14 h=176000000

88 h=176000000

h=176000000/88

h=2000000 cm

in metres    2000000/1000=2000mts

therefore height of the cylinder is 2000mts
