Diameter Radius Area Circumference of= 132
AveGali [126]

Answer:

lets \:  \: find \:  \:  \: the \:  \:  \: radius \\ 2\pi \: r = 132 \\   \frac{2\pi \: r}{2\pi}  =  \frac{132}{2\pi}  \\ r = 21.01

lets \:  \:  \: find \:  \:  \: the \:area \: now \\  = \pi {r}^{2} \\  = \pi \times  {21.01}^{2}   \\  = 1,386.76

lets \: fin d\:  \:  \: the \:  \: diameter \\  = d = 2r \\ =  d = 2 \times 21.01 \\  = d = 42.02

Among all right circular cones with a slant height of 24​, what are the dimensions​ (radius and​ height) that maximize the volum
aleksklad [387]

Answer:

5571.99

Step-by-step explanation:

We need to use the Pythagorean theorem to solve the problem.

The theorem indicates that,

r^2+h^2=24^2 \\r^2+h^2=576\\r^2=576-h^2

Once this is defined, we proceed to define the volume of a cone,

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

Substituting,

v=\frac{1}{3} \pi (576-h^2)h\\v=\frac{1}{3} \pi (576h-h^3)

We need to find the maximum height, so we proceed to calculate h, by means of its derivative and equalizing 0,

\frac{dv}{dh} = \frac{1}{3} \pi (576-3h^2)

\frac{dv}{dh} = 0 then \rightarrow \frac{1}{3}\pi(576-3h^2)=0

h_1=-8\sqrt{3}\\h_2=8\sqrt{3}

<em>We select the positiv value.</em>

We have then,

r^2 = 576-(8\sqrt3)^2 = 384\\r=\sqrt{384}

We can now calculate the maximum volume,

V_{max}= \frac{1}{3}\pi r^2 h = \frac{1}{3}\pi (\sqrt{384})^2 (8\sqrt{3}) = 5571.99
