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.
