Question

A cylinder is 5m long and radius of cylinder is 5.3cm calculate the surface area of the curved surface ? ​

Answer 1

Answer:

16642cm^2

Step-by-step explanation:

curved surface area = 2πrh

= 2 × 3.14 × 5.3× 500

= 16642cm^2

Answer 2

Question:

A cylinder is 5m long and radius of cylinder is 5.3cm calculate the surface area of the curved surface?

$\huge \blue { \bf\underline{answer}}$

$\sf\blue{radius \:of \: cylinder = 5.3m }$

$\sf\blue {length \: of \: cylinder = 5m}$

$\sf \blue{c.s.a = ...}$

$\sf\blue{we\: know.\: that \: c.s.a =2πrh</p><p>=>2×22/7×5.3×5</p><p>=>2×22/7×5.3×5</p><p>=>2×3.14×5.3×5</p><p>=>15.70×2×5.3=>5.7×10.6</p><p>==>166.42cm²}$
