Answer:
78.5
Step-by-step explanation:
A=πr^2 is the formula. Since you're using pi as 3.14, 3.14 times 5^2 is 78.5 (5^2 is 25 because 5x5=25)

, where 
.
b) 
Step-by-step explanation:
The given sequence is
.
The first term of the sequence is
The second term is 
The common ratio for this sequence can be determined using any two consecutive terms in the sequence.
Using the first two terms, the common ratio is
a) The recursive rule is given by,
, where .
b) The explicit rule is given by 
Ok, I shall help.
Please give me brainliest answer.
So first step
25x+8+9x+2=180
We can do this because they are interior angles which add to 180 degrees.
So now we simplify.
25x+9x+2+8=180
34x+10=180
Minus 10 from both sides to get x.
34x = 170
Divide by 34 to only find x.
This leaves x=5 now we find y.
9x+2=7y+5
We can make these two equal because they are alternate angles which are always equal.
Now as we established earlier x is 5 so we substitute.
9(5)+2=7y+5
45+2=7y+5
47=7y+5
Now we minus 5 from both sides to leave 7y
47-5=7y
42=7y
Now we divide by 7 to only get y.
Y=6
X=5
Hope it helps!
Plz give me brainliest answer!
I think it's 16.. idkk look it up on google
