The surface area of a cylinder is given as

$A = 2 \pi rh + 2 \pi r^2$

r (radius)= 0.75 since radius is half of the diameter
h (height) = 10

So:
$A = 2 \pi rh + 2 \pi r^2

A = 2 (3.14)(0.75)(10) + 2 (3.14)(0.75)^2

A = 47.1 + 3.5325

A = 50.6325 = 50.63in^2

Mathematics

2x + 1 = -x + 4

x = 1

x+2 = 2x+1

x= 1

-2x+2 = 13x+1

x = 1/15
