What is the surface area of a cylinder with base radius of 4 and height 5

A = 226.08

Step-by-step explanation:

The formula for the surface area of a cylinder is A=2πrh + 2πr^2

So, plug in the numbers. π (pi) = 3.14

A = (2 * 3.14 * 4 * 5) + (2 * 3.14 * 4²)

You could use a calculator for the last few steps.

Multiply what's in the first set of parenthesizes: I25.6

Now, multiply the numbers in the other pair of parenthesizes: 100.48

Lastly, add the two numbers together: 226.08

226.08 is the surface area of the cylinder.
