The difference between the volume of cone and the volume of a cylinder?
Sergeu [11.5K]

Solution:

we have been asked to find

The difference between the volume of cone and the volume of a cylinder?

As we know that the volume of the cone is given by the formula

V=\frac{1}{3} \pi r^2h\\ \\ \text{where h= height of cone, r=radius } \\

And the volume of the Cylinder is given by the formula

V= \pi r^2h\\ \\ \text{where h=Height, r=radius}\\

The difference between the volume of cone and the volume of a cylinder can be calculated as below

Difference=\frac{1}{3}  \pi r^2h-\pi r^2h=-\frac{2}{3}\pi r^2h

Machines a and t were both cleaned this week machine a is cleaned every 15 weeks and machine t is cleaned every 12 weeks what is
lapo4ka [179]

Answer:

60 weeks

Step-by-step explanation:

Factor both numbers 12 and 15:

  • 12=2\cdot 2\cdot 3;
  • 15=3\cdot 5.

Find LCM(12,15). The common factor is only 3, multiply ths common factor by all factors that remain. Then

LCM(12,15)=3\cdot 2\cdot 2\cdot 5=60.

This means that the fewest number of weeks that will pass before both machines are cleaned again in the same week is 60 weeks.

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
Tasya [4]

Answer:

\frac{dy}{dx}=-[(\frac{5x+24}{36x-6x^2})]

Step-by-step explanation:

Given function:

y =\ln(\frac{(6 - x)^{\frac{3}{2}}}{x^{\frac{2}{3}}})

we know

\ln(\frac{A}{B}) = ln(A) - ln(B)

thus,

y = \ln((6 - x)^{\frac{3}{2}}) - \ln(x^{\frac{2}{3}})

or

also,

ln(Aⁿ) = n × ln(A)

thus,

y = (\frac{3}{2})\times\ln(6 - x) - (\frac{2}{3})\times\ln(x)

therefore,

\frac{dy}{dx}=[(\frac{3}{2})\times\frac{1}{(6-x)}\times(0 - 1)] - [ (\frac{2}{3})\times\frac{1}{x}\times1]

or

\frac{dy}{dx}=-(\frac{3}{2(6-x)}) - (\frac{2}{3x})

or

\frac{dy}{dx}=-[(\frac{3(3x)+2\times2(6-x)}{2(6-x)\times(3x)})]

or

\frac{dy}{dx}=-[(\frac{5x+24}{36x-6x^2})]
