Answer:

A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)

A = 288 + 27.6 + 84

A = 399.6 m²

Step-by-step explanation:

The area =12(8x3)+(1/2)(8x6.9)+(1/2)(7x3)

The area = (288)+(27.6)+(84)

The area = 399.6 m ²

If a cylindrical tank holds 100,00 gallons of water which can be drained from thebottom of the tank in an hour, then Torricelli’

tatyana61 [14]

Answer:

First, I think the right formula is:

$V(t) = 100,000(1-\frac{t}{60} ),20\leq t\leq 60$

A) We first derive the formula given above:

$V'(t)=-\frac{100000}{60}$

V'(t) represent the drain rate of the tank volume.

B) the units is: gallons/time

C) at V'(10) = 100000/60 = 1666.66 gallons/time.

because the formula V'(t) is constant so it doesn't depend of time.
