Answer:
7 small pillows.
Step-by-step explanation:
1. Let's get rid of the whole parts of fractions -> 1 3/4=7/4, 12 1/4=49/4
2. To find how many pillows she can make divide the available fabric by the amount needed -> (49/4)/(7/4)=49/7=7.
The values of the radius and volume are placed in the formula to get the volume of the cylinder
V/ πr2
