4pi/2pi = x/360
use a proportion
2 radians equals 360 degrees
x = 720 degrees
Hope this helps
Given a term in a geometric sequence and the common ratio find the first five terms, the explicit formula, and the recursive formula. Given two terms in a geometric sequence find the 8th term and the recursive formula. Determine if the sequence is geometric. If it is, find the common ratio.
The answer to this question is C) 13
A(b+c)=a•b+a•c
18=18•1
54=18•3
18(1+3)=18•1+18•3
Good luck
Do you mean
√9 + √9 = 2√9
if so it is the answer
