The floor of a round hut is 10m in diameter. A weaver charges $15.50 to make a mat to fit the floor . Find the cost of the mat per square meter .
Work- area of a circle = 3.1 * 5*5=77.5
Cost per square meter =77.5\15.5= 5 cents per square meter

Surely you can do better than 3.1 for π
Calculators have π built-in with about 10 decimal place accuracy.
area of mat = 25π m^2
cost per m^2 = 15.5/(25π) dollars/m^2
= .197.. or <b>20 cents/m^2</b>
You found how many m^2 we can get for $1.00
