Answer:
the answer is 0
Step-by-step explanation:
220=A+S (adult plus student)
s=220-a
2.50a+1.50s=465
1.50s=-2.50a+465
s=-1.67a+310
then set those equal to each other
220-a=-1.67a+310
220=-.67a+310
-90=-.67a
.67a=90
a=60
then put a back into the first equation
220=S+A
220=s+60
s=160
a=60, s=160

Answer:
Area = 5542.488 unit^2
Circumference= 263.9 units
Step-by-step explanation:=
Given data
Radius= 42 units
Circumference= 2πr
C= 2*3.142*42
C=263.9 units
Area= πr^2
A= 3.142* 42^2
A= 3.142* 1764
A= 5542.488 unit^2
