Answer:
multiply the radius by 2π
Step-by-step explanation:
The formulas for circumference of a circle is
C = πD where D is the diameter,
or
C = 2πr where r is the radius.
Either formula is correct, but we will work with the second one since the question is asking about radius.
We see that 2π(r) = the circumference, so multiply r by 2π to get the circumference
Assume x are Erica's classes & y are Bo's classes.
x+y=35
x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes
