elixir [45]
<h2>At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.</h2>

Step-by-step explanation:

We have equation for volume of a sphere

             V=\frac{4}{3}\pi r^3

where r is the radius

Differentiating with respect to time,

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

Given that

           Radius, r = 24 cm

           \frac{dr}{dt}=0.3cm/s

Substituting

           \frac{dV}{dt}=4\pi r^2\times \frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi \times 24^2\times 0.3\\\\\frac{dV}{dt}=2171.47cm^3/min

At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.

What is the the answer to 3{2b+4} + 12b +6= 54
jarptica [38.1K]

Answer:

b=2

Step-by-step explanation:

Get rid of the parenthesis using distributive property:

6b+12+12b+6=54

Simplify

18b+18=54

subtract 18 from both sides

18b=36

divide by 18 on both sides

b=2
