A spherical balloon currently has a radius of 19cm. If the radius is still growing at a rate of 5cm or minute, at what rate is a

miv72 [106K]

Answer:

22670.8 cm³/min

Step-by-step explanation:

Given:

Radius of the balloon at a certain time (r) = 19 cm

Rate of growth of radius is, $\frac{dr}{dt}=5\ cm/min$

The rate at which the air is pumped in the balloon can be calculated by finding the rate of increase in the volume of the balloon.

So, first we find the volume of the sphere in terms of 'r'. As the balloon is spherical in shape, the volume of the balloon is equal to the volume of a sphere. Therefore,

Volume of balloon is given as:

$V=\frac{4}{3}\pi r^3$

Now, rate of increase of volume is obtained by differentiating both sides of the equation with respect to time 't'.

Differentiating both sides with respect to time 't', we get:

$\frac{dV}{dt}=\frac{d}{dt}(\frac{4}{3}\pi r^3)\\\\\frac{dV}{dt}=\frac{4\pi}{3}(3r^2)(\frac{dr}{dt})\\\\\frac{dV}{dt}=4\pi r^2(\frac{dr}{dt})$

Now, plug in 19 cm for 'r', 5 cm per minute for $\frac{dr}{dt}$ and solve for $\frac{dV}{dt}$ . This gives,

$\frac{dV}{dt}=4\pi (19 cm)^2(5\ cm/min)\\\\\frac{dV}{dt}=4\times 3.14\times 361\times 5\ cm^3/min\\\\\frac{dV}{dt}=22670.8\ cm^3/min$

Therefore, the rate at which the air is being pumped into the balloon is 22670.8 cm³/min.

Vance weighs 250 pounds and is losing 5 pounds each month. Phillip weighs 200 pounds

Lelu [443]

Answer:

250-5m=200+4m ; 5.56 months

Step-by-step explanation:

<u>Let's start this question by writing two expressions that depict the situation.</u>

Vance: 250-5m

This simply means that Vance currently weighs 250 pounds, and every month he is losing 5 pounds. (m=number of months)

Phillip: 200+4m

This is essentially the same thing. Phillips starting weight is 200, but here we use an addition sign because he is gaining 4 pounds every month as opposed to losing it.

To find the number of months it'll take for them to weigh the same, we just need to equate the values and solve for m.

<u>Our equation would then be:</u>

250-5m=200+4m

Let's solve the equation by bringing the variables to one side and the numbers to the other.

250-5m=200+4m

Subtract 4m from both sides

250-5m-4m=200+4m-4m

250-9m=200

Subtract 250 from both sides

250-250-9m=200-250

-9m=-50

Divide both sides by -9

m=5.556

So it will take about 5 months and a half to weigh the same.
