Answer:
10.2π
Step-by-step explanation:
Given data
Area of circle= 81 ft^2
Also, the expression for the area of a circle is
A=πr^2
substitute
81=3.142*r^2
r^2= 81/3.142
r^2= 25.77
square both sides
r= √25.77
r= 5.1
Also, the expression for the circumference is
C= 2πr
substitute
C= 2*π*5.1
C= 10.2π
Hence the circumference is 10.2π
So there are 6 different grade levels with 3 classes in each. So 6*3 = 18 classes total.
<span>If there are approximately 27 children in each class, than 27*18 = ? your answer.</span>
The answer to the missing value is X = 3
