$\%$ Problem $2\mathrm{.}8$

$\%$ a$)$ The volume of a cylinder is v$=$ pi $*$ r$^2*$h

$\%$ Define the radius, r$,$ as $3$ and the height, h$,$ as the matrix

$\%$ h $=[1,5,12]$

r $=3$;

h $=[1,5,12]$;

$\%$ Find the volume of the cylinders by performing an array calculation. This means you must use array operators

$\%$ Your answer should be an array named vol.

$\%$ Enter the code to find the volume, vol here

$\%$ b$)$ The area of a triangle is $1/2$ the length of the base of the triangle, times the height of the triangle.

$\%$ Define the base as the matrix

$\%$ b $=[2,4,6]$

$\%$ and the height, h$,$ as $12.$

$\%$ Find the area of the triangles by performing an array calculation. Your answer should be an array named area.

b $=[2,4,6]$;

h $=12$;

$\%$ Enter the code to find the area, named area, here

$\%*********************************************************************$

$\%$ Although you don't have to use the $.*$ operator for both

$\%$ multiplications and the $./$ for the division it won't hurt if you do

$\%$ and is good practice

$\%*************************************************************************$

$\%$ c$)$ The volume of any right prism is the area of the base of the prism, times the vertical dimension of the prism.

$\%$ The base of the prism can be any shape, for example a circle, a rectangle or a triangle.

$\%$ Find the volume of the prisms created from the triangles in part b of this problem.

$\%$ Assume that the vertical dimension of these prisms is $6.$ Once again you must use an array calculation. Your answer should be an array named vol$\_$prism.

$\%$ Redefine h here

$\%$ Calculate the volume of the prisms here and name the result vol$\_$prism
