Answer:
radius : 29.99 feet
Area : 2824.57 square feet
Step-by-step explanation:
The first term in the series is 336. The second term is obtained by subtracting 4 from the first term; subtract 4 from that to get the third term; and so on. Then the <em>n</em>-th term in the series is
336 - 4 (<em>n</em> - 1)
or
340 - 4<em>n</em>
The last term in this series is 4, so we solve for <em>n</em> :
340 - 4<em>n</em> = 4
336 = 4<em>n</em>
<em>n</em> = 336/4 = 84
The sum of the series is then
Recall that
Then the sum we want is
I would have to go with C. i might be wrong hope its right if it is rate please
Answer:
Below
Step-by-step explanation:
To prove that the diagonals bisect each other we should prove that they have a common point.
From the graph we notice that this point is E.
ABCD is a paralellogram, so E is the midpoint of both diagonals.

Let's start with AC.
● A(0,0)
● C(2a+2b,2c)
● E( (2a+2b+0)/2 , (2c+0)/2)
● E ( a+b, c)
●●●●●●●●●●●●●●●●●●●●●●●●
BD:
● B(2b,2c)
● D(2a,0)
● E ( (2a+2b)/2 , 2c/2)
● E ( a+b ,c)
●●●●●●●●●●●●●●●●●●●●●●●●●
So we conclude that the diagonals bisect each others in E.
Answer: The height would be 8 hope this helps!!
