Compute the square footage of carpet needed to cover a room 12' 3" x 18' 4".

baherus [9]

convert inches to feet

3/12 = 0.25 feet so 12'3" = 12.25 feet

4/12 = 0.33 feet so 18'4" = 18.33 feet

now multiply both of them

12.25 x 18.33 = 224.54 square feet

The tires on a new compact car have a diameter of 2.0 ft and are warranted for 63,000 miles. (a) Determine the angle (in radians

Damm [24]

Answer:

Tire will be warranted for $3.326\times 10^8radian$

Step-by-step explanation:

We have given that tire is warranted for 63000 miles

We know that 1 mile = 5180 feet

So $63000miles=63000\times 5280=3.3264\times 10^8feet$

Diameter is given d = 2 feet

So radius $r=\frac{d}{2}=1feet$

Angular distance is given by $\Theta =\frac{linear\ distance}{radius}=\frac{3.326\times 10^8}{1}=3.326\times 10^8radian$

Find volume of cone z=sqrt(x^2+y^2) that is bounded with z=5 and z=7

Nina [5.8K]

Convert to cylindrical coordinates first, using

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}$

Then the volume is

$\displaystyle\int_{\zeta=5}^{\zeta=7}\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=\zeta}r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta$
$=\displaystyle\pi\int_{\zeta=5}^{\zeta=7}\zeta^2\,\mathrm d\zeta$
$=\dfrac{218\pi}3$
