Answer:
22.2
Step-by-step explanation:
By definition we have the relationship between the diameter of a circle and its radius is as follows:
r = d / 2
where
r: radio
d: diameter
Since the diameter of the circle is 4, then the radius will be given by
r = (4) / 2 = 2
answer
the radius of the circle is 2 units.
Answer:
<h2>400</h2>
Step-by-step explanation:

Answer:
a
Since the integral has an infinite discontinuity, it is a Type 2 improper integral
b
Since the integral has an infinite interval of integration, it is a Type 1 improper integral
c
Since the integral has an infinite interval of integration, it is a Type 1 improper integral
d
Since the integral has an infinite discontinuity, it is a Type 2 improper integral
Step-by-step explanation:
Considering a

Looking at this we that at x = 3 this integral will be infinitely discontinuous
Considering b

Looking at this integral we see that the interval is between
which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral
Considering c

Looking at this integral we see that the interval is between
which means that the integral has an infinite interval of integration , hence it is a Type 1 improper integral
Considering d

Looking at the integral we see that at x = 0 cot (0) will be infinity hence the integral has an infinite discontinuity , so it is a Type 2 improper integral
