Swimming pool is circular with a 40-ft diameter. The depth is constant along east-west lines and increases linearly from 2 ft at the south end to 7 ft at the north end. Find the volume of the water in the pool. Explain your reasoning for full credit.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

angle addition postulate

2x=56

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
