Question

The radius of a right circular is 7cm and its height is 14cm .find it curved surface area and total surface area

Answer 1

$here \: is \: your \:answer$

h = 14 cm

r = 7 cm.  

So,
$( \sqrt{ {7 }^{2} + {14}^{2} } ) = \sqrt{245 } = \sqrt[7]{5}$
∴ ᵗᵒᵗᵃˡ ˢᵘʳᶠᵃᶜᵉ ᵃʳᵉᵃ =

πrl +πr² =

 =1545 +1 

= (3.236 x 154) sq.cm   

= 498.35 sq.cm

$hope \: it \: helps$

Answer 2

h = 14 cm

r = 7 cm.

So,

( \sqrt{ {7 }^{2} + {14}^{2} } ) = \sqrt{245 } = \sqrt[7]{5}(

∴ ᵗᵒᵗᵃˡ ˢᵘʳᶠᵃᶜᵉ ᵃʳᵉᵃ =

πrl +πr² =

=1545 +1

= (3.236 x 154) sq.cm

= 498.35 sq.cm
