Answer:
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.
