Step-by-step explanation:
Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r
r=35.03
Diameter is 2*radius
Diameter = 
= 70.06
Hence, diameter of the circle is 70.06 feet.
For this question, I would first see what one child is equal toby divide the children by the percentage.
15÷3= 5
Each child is worth 5%. If you know each child is worth 5%, and the total number of students are 100%, then you can divide.
100÷5= 20
There are 20 students in the class. To make sure our answer is right, we can check to see if 3 students are 15 percent.
3÷20= .15×100= 15
So yes, there are 20 students in the class.
