Answer:

420,000

Step-by-step explanation:

If 140,000 is \frac{1}{3} of what she had yesterday, then you just multiply the number by 3 because \frac{1}{3} times 3 is \frac{3}{3}, which is 1.

the radius of a sheridan balloon is increasing at a rate of 3 centimeters per minute. how fast is the volume changing when the r
san4es73 [151]

The volume of the balloon is 2352\pi cc/min

Explanation:

The radius of the balloon is increasing at a rate of 3 cm/min.

To determine the volume of the balloon when the radius is 14 cm, we shall use the formula V=\frac{4}{3} \pi r^3

The rate of change of r with respect to time t is given by,

\frac{d}{d t}(r)=3 \mathrm{cm} / \mathrm{minute}

Now, we shall determine the \frac{d}{d t}(V)

\begin{aligned}\frac{d}{d t}(V) &=\frac{d}{d t}\left(\frac{4}{3} \pi r^{3}\right) \\&=\frac{4}{3} \pi\left(3 r^{2}\right)\frac{d}{d t}(r) \\&=4 \pi r^{2}\frac{d}{d t}(r)\end{aligned}

Now, we shall determine the \frac{d}{d t}(V) at r=14 \mathrm{cm} and substituting \frac{d}{d t}(r)=3 \mathrm{cm} / \mathrm{minute}, we get,

\begin{aligned}\left(\frac{d V}{d t}\right)_{r=14} &=4 \pi r^{2} \frac{d}{d t}(r)\\&=4 \pi(14)^{2} (3)\\&=4 \pi 196 (3)\\&=2352\end{aligned}

Thus, The volume of the balloon is 2352\pi cc/min
