$\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})~\hspace{10em} slope = m\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-2(x-1)$

CaHeK987 [17]

Answer:

The height of the sorcerer's hat is 17.98 inches.

Step-by-step explanation:

Given : A sorcerer's hat is shaped like a cone with a diameter of 8 inches and a volume of 301.6 cubic inches.

To find : What is the height of the sorcerer's hat ?

Solution :

The volume of the cone is given by, $V=\frac{1}{3}\pi r^2 h$

The diameter of cone is d=8 inches.

The radius of cone is r=4 inches.

The volume of cone is V=301.5 cubic inches.

Substitute the value,

$301.5=\frac{1}{3}\times \frac{22}{7}\times (4)^2\times h$

$h=\frac{301.5\times 3\times 7}{22\times 16}$

$h=17.98$

Therefore, the height of the sorcerer's hat is 17.98 inches.
