Soo lets take anna=2a sun=2a and amanda=a
2a+2a+a=45
5a=45
a=45/5
a=9
then anna and sun=18 and amanda=9
and if we compare the diff annas dollars from attachment and the work shown above = 18-15=3
soo the answer should be three
ANSWER
D. 18 m^2
EXPLANATION
The area of a kite is half the product of the diagonals.
The diagonals of the kite are
3+3=6m
and
2+4=6m
The area of the kite
![= \frac{1}{2} \times 6 \times 6](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%206%20%5Ctimes%206)
![= 3 \times 6](https://tex.z-dn.net/?f=%20%3D%203%20%5Ctimes%206)
![= 18 {m}^{2}](https://tex.z-dn.net/?f=%20%3D%2018%20%7Bm%7D%5E%7B2%7D%20)
The correct answer is D.
The volume of the tank of water is 653.12 cubic meters.
<h3>
How to get the volume?</h3>
For a cylinder of height H and diameter D, the total volume is given by:
![V = 3.14*(D/2)^2*H](https://tex.z-dn.net/?f=V%20%3D%203.14%2A%28D%2F2%29%5E2%2AH)
In this case, we know that:
D = 8m
H = 13m
Replacing that in the above equation:
![V = 3.14*(8m/2)^2*13m = 653.12 m^3](https://tex.z-dn.net/?f=V%20%3D%203.14%2A%288m%2F2%29%5E2%2A13m%20%3D%20653.12%20m%5E3)
So the volume of the tank of water is 653.12 cubic meters.
