A spherical balloon is inflated so that its volume is increasing at the rate of 3 ft3/min. How fast is the diameter of the ballo

beks73 [17]

When an spherical balloon volume is increasing at the rate of $3ft^3/min$ then the diameter of the balloon is increasing $\frac{3}{2\pi }ft /min$

How can we find the rate of change of balloon's diameter ?

The volume of a spherical balloon is $v=\frac{4}{3} \pi r^3$

In form of diameter we can write as

$v=\frac{4}{3} \pi (\frac{D}{2} )^3\\=\frac{1}{6} \pi D^3$

Now we will differentiate both sides wrt to $t$ we get

$\frac{dv}{dt} =\frac{1}{6} \pi 3D^2 \frac{dD}{dt} \\\frac{dD}{dt} =\frac{2}{\pi D^2} \frac{dv}{dt} \\\\when r=1\\D=2ft$

Given in the question $\frac{dv}{dt} =3ft^3/min$

thus when we substitute the values we get

$\frac{dD}{dt} =\frac{2}{\pi *2^2} (3)\\\frac{dD}{dt}=\frac{3}{2\pi } ft/min$

<h3>Answer:</h3>

67 miles

<h3>Step-by-step explanation:</h3>

On Monday, Jullo ran <u>39 miles.</u>

⇒ Monday = 39 miles

On Tuesday, he ran <u>24 miles.</u>

⇒ Tuesday = 24 miles

On Wednesday, he ran <u>4 miles.</u>

⇒ Wednesday = 4 miles

<u>Finding the total miles:</u>

Total miles ran on Monday, Tuesday, and Wednesday = 39 + 24 + 4

= 67 miles
