Answer 2

★ GivEn ThaT :-

A Cylinder whose

• Radius = 20/2 = 10 cm
• Height = 16 cm

★ To FinD :-

• Curved Surface Area (CSA) of Cylinder

★ ForMulAe To bE UseD :-

${\large{\blue{\boxed{\underline{\pink{\texttt{C.S.A. \: of \: the \: Cylinder \: = \: 2πrh}}}}}}}$

★ SoLuTioN :-

Then,

$\sf{C.S.A. \: of \: the \: Cylinder }$

$\sf{ = \: 2 \times \frac{22}{7} \times 10 \times 16 \: {cm}^{2} }$

$\sf{ = \frac{7040}{7} \: {cm}^{2} }$

$\sf\orange{\underline{ =\: 1005.7 \: (approx) \: {cm}^{2} }}$

Which is your required answer!!
