Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling 
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term , is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... () 
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation. is pretty close to 3.14.
160 3.14 = 502.4, which is decently close to our other answer.
Hope this helps!

For
to be continuous at
, we need to have
Note that
means that
, but that
is *approaching* 5. We're told that for
, we have
We can write
and the limit would be
and so
is discontinuous.
Equation for circumference is c = 2(pi)r
r = 1/2(d)
d = 20
So…. r = 1/2(20) = 20/2 = 10
Going back to circumference equation
c = 2(pi)(10) = 2(3.14)(10) = 62.8
