Answer:

120πcm²

Step-by-step explanation:

Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.

First we need to figure out the area of the top circle and bottom circle.

We know that the formula for the area of a circle is:

πr²

So we need both circles, our formula becomes:

2πr²

Let's substite our radius in.

2 × π × 4² = 32πcm²

Now we need to find the area of the sides itself. Our formula here is:

2 × π × r × h

Let's substitute our radius and height in:

2 × π × 4 × 11 = 88πcm²

Let's now add both of these together:

88πcm² + 32πcm² = 120cm²

Remember to add your measurements!

Hope this helped!

what is the answer?
