A cylinder is inscribed inside of a square prism so that touches each face of the rectangle or prism. The empty space outside of

the cylinder, but inside of the prism is to be filled with a liquid epoxy. If the cylinder has a circumference of 84.78 cm and the writing either prism is 40 cm tall, how many cubic centimeters of epoxy will be required to completely fill the empty spaces?

To solve take  (Volume of Prism) - (Volume of Cylinder) = Epoxy

<span>V=(Area of base)(height) 
</span>
Both they Cylinder and prism have a height of 40 inches 
we can find the sides of the base of the prism by finding the diameter of the cylinder.

C=πd    so  84.78 = πd.

Divide both sides by Pi (3.14)
\frac{84.78}{3.14} = 27

Half of the diameter is the radius to find the area of the cylinder base. 27/2=13.5

The volume of Prism is found by
V=l*w*h

 27*27*40 = 29160 sq cm

The volume of cylinder is found by
V= \pi r^{2}h

using  3.14* 13.5^{2}*40 = 22890.6

29160 - 22890.6 = 6269.4 cubic centimeters

PLEASE HELP ME URGENT

Answer:

Hello! answer: 39

Step-by-step explanation:

Formula for triangles area: base × height ÷ 2

Formula for squares area: base × height

5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39

Rearranging literal equations!! really confused ASAPplease
valina [46]

Answer:

b = \frac{8a-55}{5-a}

Step-by-step explanation:

To clear the radicals square both sides

\frac{1}{6-a} = \frac{8+b}{b-7} ( cross- multiply )

(6 - a)(8 + b) = b - 7 ← expand factors on left using FOIL

48 + 6b - 8a - ab = b - 7 ( subtract 48 from both sides )

6b - 8a - ab = b - 55 ( add 8a to both sides )

6b - ab = b - 55 + 8a ( subtract b from both sides )

6b - ab - b = 8a - 55, that is

5b - ab = 8a - 55 ← factor out b from each term on the left side )

b(5 - a) = 8a - 55 ← divide both sides by (5 - a)

b = \frac{8a-55}{5-a}
