Answer 1

345.4 using the 3.14 for pi

345.6 using the pi button

Explanation:

The surface area of a cylinder is given by

SA=2 pi rh+2 pir^2

The radius is 5 and the height is 6

SA = 2·pi·5·6+2·pi·5^2

SA = 60pi + 50pi

110pi

Letting pi = 3.14

SA =345.4

Letting pi = pi button

= 345.57519 = 345.6
