radius is half the diameter
18/2 is 9 so the radius is 9in
Answer:
C and D
Step-by-step explanation:
i=√-1
n/4=x.5
since 2 is the remainder
n=2x
then i^n=i^2x
when x is even, i^n =1
when x is odd, i^n=-1
25 squared is just 25 times 25 which equal 625
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -22
