The formula for the surface area is given and as follows.

SA = (2)(3.14)(r^2) + (2)(3.14)(r)(h)

The radius of the cylinder is 4 inches and the height is 9 inches. Using the given values, we can plug them into the formula and solve for the surface area from there.

SA = (2)(3.14)(4^2) + (2)(3.14)(4)(9)

SA = (6.28)(16) + (6.28)(36)

SA = 100.48 + 226.08

SA = 326.56 in^2

Hope this helps!! :)

Answer:

The answer to your question is   SA = 326.56 in²

Step-by-step explanation:

Data

pi = 3.14

height = 9 in

radius = 4 in

Formula

     SA = 2πr² + 2πrl

Process

This process is very easy to solve because we have all the values and the formula so, just substitute the values and simplify.

-Substitution

     SA = 2(3.14)(4)² + 2(3.14)(4)(9)

-Simplification

     SA = 100.48 + 226.08

-Result

    SA = 326.56 in²
