For every 100 students, 72 prefer pizza.
The are 15 groups of 100 students each amongst 1500 students;
The total number of students preferring pizza then is;
15*72= 1080
To find the circumference of a circle you multiply pi (3.14) by the diameter ad to find the area you multiply pi (3.14) times the radius squared
Since the circumference is 31.4 divide that by pi to find the diameter which is 10
The radius of a circle is half of the diameter, so for this circle the radius is 10 / 2 = 5
Take the radius and square it : 5^2 = 25
Then multiply the squared radius by pi (3.14) to find the are : 25 * 3.14 = 78.5
So the area of this circle is 78.5 centimeters squared
