Question

Calculate the capacity of a hemispherical tank of diameter 10

Answer 1

Step-by-step explanation:

volume = (4/3) pi r^3

r = 5 meters

so

volume = (4/3) pi * 125 m^3

rate through hose = pi r^2 * 2 m^3/s = pi .2*.2 * 2 = .08 pi m^3/s

so

t in seconds = 167 pi / .08 pi

in minutes 167 / (.08 *60) = 34.7 min
