Answer:
378.33 minutes
Step-by-step explanation:
From the question, we're told that
Length of the side of the square, l = 4 m
Then the current volume of water = (4 m)³ = 64 m³3 = 64,000 Liters
64,000 + [∫(20 - t) dt from 0 to t] = 0, solving the integral, we have
20t - (t^2)/2 = -64,000, multiplying all by 2 so as to eliminate the fraction
40t - t^2 + 128,000 = 0
t^2 - 40t - 128,000 = 0, on solving the quadratic equation(using general formula), we find that
t = 378.33 minutes
500 milliliters. Divide 1000 ml (1 liter) by 2 ml to get the answer.
Answer:
A. (125.6 in)
Step-by-step explanation:
R = d / 2 = 40 / 2 = 20 in
Circumference is:
S = 2*π*R=2*3.14*20=125.6 in
