Answer:
120πcm²
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!
