A triangular prism is composed of 2 triangles and 3 rectangles.

1 triangle has 2 right triangle, for a total of 4 right triangles.

Area of a right triangle = ab/2 = (3.5m * 2m)/2 = 7/2 = 3.5m²
3.5m² x 4 right triangles = 14 m² total area of the triangle bases.

Rectangle: length = 11 m ; width = 4m
Area of a rectangle = L * W = 11m * 4m = 44m²
44m² x 3 rectangles = 132 m² total area of the rectangle faces

Surface area = 132 m² + 14 m² = 146 m²

6) A cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet. How much water can the silo hold, in terms of π?

Natali5045456 [20]

The amount of water silo can hold in terms of π is 324π cubic feet

<h3><u>Solution:</u></h3>

Given that cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet

To find: Amount of water silo can hold in terms of π

This means we are asked to find the volume of cylindrical shaped silo

<em><u>The volume of cylinder is given as:</u></em>

$\text {volume of cylinder }=\pi \mathrm{r}^{2} \mathrm{h}$

Where "r" is the radius of cylinder

"h" is the height of cylinder

π is the constant has a value 3.14

Given diameter = 18 feet

$radius = \frac{diameter}{2} = \frac{18}{2} = 9$

Substituting the values in formula, we get

$\text {volume of cylinder }=\pi \times 9^{2} \times 4$

$\text {volume of cylinder }=\pi \times 81 \times 4=324 \pi$

Thus amount of water silo can hold in terms of π is 324π cubic feet

Two rectangular prisms are shown. The prisms have the same dimensions. What is the total volume of both prisms?

azamat

Answer:

V= 2* L*B*H

Step-by-step explanation:

Although we are not given the dimension of the rectangular prisms in this question

The volume of a rectangular prism is

V= L*B*H

Since the number of the prism is two

Hence the volume of the two prisms

V= 2* L*B*H

Therefore, when the plugin the dimensions of the prism into the expression above, you will get the volume of the two prisms combined
