lapo4ka [179]
This is the concept of application of geometry and financial mathematics; To calculate for the total cost of the carpet we proceed as follows;
Total cost=[area of the carpet]*[price per square yard]
area of carpet is given by:
Area=πr^2
where;
radius,r=6 yeards
=π*6^2
=113.1 square yards
therefore the price of the carpet will be:
113.1*14
=$1,583.4

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 m
daser333 [38]

Answer:

\dfrac{dV}{dt}=502.65\ mm^3/s

Step-by-step explanation:

The volume of a sphere is given by :

V=\dfrac{4}{3}\pi r^3

The rate of change of volume means,

\dfrac{dV}{dt}=\dfrac{d}{dt}(\dfrac{4}{3}\pi r^3)\\\\\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r\times \dfrac{dr}{dt}

We have, \dfrac{dr}{dt}=2\ mm/s\ and\ r=40\ mm

So,

\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3\times 20\times 2\\\\=502.65\ mm^3/s

So, the volume is increasing at the rate of 502.65\ mm^3/s.
