To function properly, a rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance. a 40 feet long rainwater pipe runs under the edge of a root. what is the verifical distance, in inches, the pipe must drop between its ends? round your answer to the nearest tenth.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
