Answer:

Using 3.14  for pi

835.24 cm^2

Using the pi button for pi

835.6636459 cm^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi r h

     = 2 * pi ( 7)^2 + 2 pi ( 7) * 12

    = 98 pi + 168 pi

    =266 pi

Using 3.14  for pi

835.24 cm^2

Using the pi button for pi

Answer:

226[tex]\pi[/tex] or 835.664

Step-by-step explanation:

Surface area of a right cylinder= 2πrh+2πr^2

=2π7✖️12+2π49

=226π

Hope this helped, and have a nice rest of your day!
