Answer:
The radius of the circle is 1.
Step-by-step explanation:
The way to find the radius of a circle is to divide the diameter by 2.
The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i
Step-by-step explanation:
We know that

We can use the smaller powers of i to solve the larger powers.
a. i^27=−i

b. i^28=i

c. i^14=1

d. i^8=1

e. i^5=i

Hence,
The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i
