Surface area

The surface area of a cylinder is:

$A_{cylinder} = 2\pi r^2+2\pi rh=2\pi r(r+h)$

Hence, the solution is quite simple:

$A_{cylinder} = \frac{22}{7}\cdot2\cdot 0.75 \text{ feet }\cdot(0,75 + 3)\text{ feet }\approx 17.678\text{ feet}^2$

The surface area is equal to the lateral area plus the area of the two bases. We have

$A=\dfrac{22}{7}(1.5)(3)+2\left(\dfrac{22}{7}\right)\left(\dfrac{1}{4}\right)(1.5)^2=$ $\color{#D61F06}\boxed{17.68~square~feet}$
