Using the combination formula, it is found that she can select the shirts in 775,200 ways.
The order in which the shirt are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
Combination formula:
is the number of different combinations of x objects from a set of n elements, given by:
In this problem:
- 3 shirts from a set of 17.
- Then, 3 shirts from a set of 20.
- They are independent, hence, to find the total, we multiply both combinations.
She can select the shirts in 775,200 ways.

Answer:
113.04 units^2
Step-by-step explanation:
The area of a circle can be found using:
First, we need to find the radius, since we have the diameter.
<u />
<u><em>Radius</em></u>
The radius is half the diameter, or
r=d/2
We know the diameter is 12, so we can substitute that in
r=12/2 <em>Divide </em>
r=6
<u><em>Area </em></u>
Now we know the radius and can substitute it into the area formula
<em>Solve the exponent </em>
Substitute 3.14 in for pi
a=3.14*36 <em>Multiply </em>
a=113.04
We aren't given a specific unit, so we can say the area is
113.04 units^2
