What is the surface area of a cylinder with a diameter of 2 and a height of 12

note: answer must not be fraction or decimal

surface area = 2 x pi x r x h + 2 x pi x r^2

2 x (3.14) x 1 x 12 = 75.36

2 x (3.14) x 1^2 = 6.28

75.36+6.28 = 81.64

 if you cant use a fraction or decimal, does the answer need to be in terms of pi?

that would be 2 x PI x r x h = 2 x pi x 1 x 12 = 24PI

2 x PI x r^1 = 2 x PI x 1 = 2PI

24 PI x 2 PI = 26 PI

its 50 miles away from the starting point
