5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.

Try the first one, it looks right since it’s all in sequenced right
Circumference= 2 times pi times radius
c=2pir
divide both sides by 2pi
c/(2pi)=r
c=12.6
12.6/(2 times pi)=12.6/2 times 1/pi=6.3 times 1/pi=6.3/pi
radius=6.3/pi=aprox (pi aprox 3.14) 2
Answer:
factored form
Step-by-step explanation:
example
(x + 2)(x + 3) ← is an expression in factored form
= x² + 5x + 6 ← in expanded form
