For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do

of a piece per minute. Luke on the other hand can do

of a piece per minute.
To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign

as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as

.
Putting this into an equation we'll get:




Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
ANSWER: Mia made 52 pieces of origami.
The area of the shaded face of the cylinder is 1,520 mm².
<h3>How to find the area of the shaded area?</h3>
We can see that the shaded area of the cylinder is circular in shape.
This means that we can find the area of the shaded area by finding the area of the circle.
The radius of the circle is given as 22 mm.
The formula for finding the area of a circle is given as:
<em>Area = πr²</em>
= 3.14 × 22 × 22
= 1,519.76
≈ 1520 mm²
Therefore, we have found the area of the shaded face of the cylinder to be 1,520 mm².
