'of' means multiply

convert 3 and 1/2 to a improper fraction for easier mutlipying
3 and 1/2=3+1/2=6/2+1/2=7/2

a dozen is 12 eggs

7/2 of a dozen means
7/2 times 12=84/2=42

that is 42 eggs

There are 12 eggs in a dozen. We can set up a cross-multiplication problem to solve this. 12/100=3.5/x 

3.5 times 100 is 350, or two decimal places to the right. 12 times x is 12x. Now we can solve for x.

12x=350

divide 12 on both sides to isolate x.

350 divided by 12 is 29.1666667

so 3.5 is 29.66666667 of 12.

The area of the entire circle is A = πr², or A = π(2 in)².

This corresponds to a central angle of 2π radians, or 6.28 radians.

The area of the sector described above is just a certain fraction of that:

4.3 rad

-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²
