Help I will be marking brainliest!! Jensen has an above ground pool in the shape of a regular octagon. Opposite sides are 25 feet apart and each side is 10.4 feet long. It requires 7.5 gallons to fill one cubic foot. How much water is need to fill the pool with 3 feet of water.

A. 3900
B. 5850
C. 1560
D. 11700

Show work, if possible. Thanks❤️

Given: base = 10.4ft, height = 12.5

Area of octagon = 8(1/2 × b × h)

Volume of pool = 520ft² × 3ft

Now, 1 cubic ft takes 7.5 gallons to fill.

Therefore, 1560 cubic ft takes,

So, Correct choice - [D] 11,700.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
