Step 1

In this question we will use basic of geometry i.e formula of volume of triangular pyramid and volume of cylinder.

We will use volume of triangular pyramid=

Volume of cylinder

Solution of the above problem is in the step below.

(a)

As we know the formula of Volume of triangular pyramid

So,

Volume of pyramid

As we can observe that

Area of base

Height of triangular pyramid =8m

Hence,

Volume of pyramid

Volume of triangular pyramid

(b)

As we know that the volume of cylinder$=\pi {r}^{2}h$

Where; r= radius of cylinder =1.8 ft

h= Height of cylinder =4 ft

So,

Volume of cylinder$=\pi {\left(1.8\right)}^{2}\left(4\right)$

Volume of cylinder$=40.6944f{t}^{3}$

As we know that the volume of cylinder

Where; r= radius of cylinder =1.8 ft

h= Height of cylinder =4 ft

So,

Volume of cylinder

a) Use Coordinate Geometry Computations to compute the intersection point of the lines AB and CD. The X and Y coordinates of stations A, B,C and D in feet are given as follows:

${X}_{A}=8377.66\text{}{Y}_{A}=4340.92$

${X}_{B}=8719.43\text{}{Y}_{B}=4642.65$

${X}_{C}=84.36.76\text{}{Y}_{C}=4712.64$

$X-\left\{D\right\}=8810.45\text{}{Y}_{D}=4325.72$

b. Use an alternative method (e.g. analytical geometry) to compute the intersection point.
