The Curved surface area of. a right circular cylinder is 4.4 sq.cm. The radius of the base is 0.7 cm. The height of the cylinder will be

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\underline{\boxed{\bold\blue{Answer}}}$

$\underline{\boxed{\bold\purple{Given}}}$

$\red\leadsto\orange { 0.7m}$

$\red\leadsto\orange {CSA = 4.4m²}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\green{CSA \: of \: cylinder = 2πrh}$

$\red\leadsto\orange{2πrh = 4.4m2}$

$\green{Let \: h \: be \: x}$

$\red\leadsto\orange{2× \frac{22}{7}×0.7x = 4.4}$

$\red\leadsto\orange{x = \frac{4.4×7}{2×22×0.7} = 1m}$

$\red\leadsto\orange{x = \frac{30.8}{30.8} = 1m}$

$\red\star\orange{ \: \: Height = 1m}$

[Hope this helps you.../]
