Answer:

9/2π cm/s

Step-by-step explanation:

Volume of the spherical balloon V= 4/3πr³

Rate of change of volume dV/dt = dV/dr * dr/dt

dV/dr = 3(4/3πr²)

dV/dr = 4πr²

dV/dr = 4π(2)²

dV/dr = 16π

If V = 72cm²/s

72 = 16π*dr/dt

dr/dt = 72/16π

dr/dt = 9/2π cm/s

Hence the radius is changing at 9/2π cm/s

Answer:

11.4

Step-by-step explanation:

So we know that Triangle ACB is similar to Triangle EFD.

This means that their sides are proportional to each other.

We want to find x or side AB. To do so, we can set up a proportion.

The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

$\frac{AB}{ED}=\frac{BC}{DF}$

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

$\frac{x}{3.8}=\frac{15}{5}$

Reduce the right:

$\frac{x}{3.8}=\frac{3}{1}$

Cross multiply:

$x=11.4$

So, the value of x is 11.4

And we're done!
