Suppose the radius of the sphere is increasing at a constant rate of 0.3 centimeters per second. At the moment when the radius i

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.

stiv31 [10]

Answer:

Total number of result at two polling location in a page election is represented by expression 8r + 11.

Solution:

Given that a page election result can hold r result.

Number of result at one polling location = 5r + 15

Number of result at second polling location = 3r - 4

Need to write simplified expression for total number of results at two polling location.

Total number of results at two polling location = Number of result at one polling location + Number of result at second polling location

=> Total number of results at two polling location = (5r + 15) + (3r - 4) = 8r + 11

Hence total number of result at two polling location is represented by expression 8r + 11.
