Answer:

about 28

Step-by-step explanation:

you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)

AB = 19* (sin 75/ sin ( 180 -75-64) )

AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...

Step-by-step explanation:

step 1

Find the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=\pi r^{2} +2\pi rh$

we have

$r=3/2=1.5\ in$ ----> the radius is half the diameter

$h=5\ in$

assume

$\pi =3.14$

substitute

$SA=(3.14)(1.5)^{2} +2(3.14)(1.5)(5)=54.165\ in^{2}$

Find the cost

$54.165*(0.75)=\$40.62$

step 2

Find the surface area of the square prism

The surface area of the prism is equal to

$SA=b^{2} +4bh$

we have

$b=3\ in$

$h=5\ in$

substitute

$SA=(3)^{2} +4(3)(5)=69\ in^{2}$

Find the cost

$69*(0.75)=\$51.75$

step 3

Find the difference of costs

$\$51.75-\$40.62=\$11.13$
