#

by surface area i suppose the total surface area

#

can you tell me the surface area of the circle (just the normal area of the circle)?

#

when you get that multiply it by 2 because you have 2 circular faces like that in a cylinder and add the curved surface area of the cylinder

#

voila

#

that is ur total surface area my G

#

welcome betmen

Just take the integral of it

#

To find the surface area of a cylinder= 2πr²+h2πr
Where h is the height and r is the radius

#

So to solve your cylinder

#

2π(7)²+2(2)π(7)

#

2π49+4π7

#

98π+28π

#

126π

#

=395.84067....
