Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
The equation for finding the area of a circle of A=pi(r^2). Just plug in r=4 to find the area:
A=pi(4^2)
A=16pi
A=50.27 units squared

Answer:
10 is your answer
Step-by-step explanation:
√((100 * 2)/2)
Simplify. First, follow the Parenthesis. Combine 100 with 2
100 * 2 = 200
Next, divide by 2
200/2 = 100
Root 100
√100 = √10 * √10 = 10
10 is your answer

An easier way to solving this is to first cancel out the 2's ( multiplying 2 and dividing 2 would do nothing), and just square rooting 100, giving you the answer 10.
