Find the surface area of a square pyramid with a length of 5 cm and a slant height of 8cm.

Mathematics

Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area  of while pyramid = 4 * 20 + 25 = 105 cm^2

Volume of the cone = (1/3) pi r^2 h
  = (1/3) pi * 5^2 * 8
  =  209.44  ft^2

ollegr [7]

Reflecting the triangle ABC implies that the new position would be a mirror of the previous position

The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W

<h3>How to determine the next step</h3>

After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.

This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point

Hence, the statement that logically comes next is (c)

The length and
Iteru [2.4K]

Answer:

42 yards

Step-by-step explanation

There are 4 sides to a rectangle. 2 lengths, and 2 widths. That means that you multiply both values by 2 and then add them together, so 40 + 2. A more basic way to think of it is 20+20+1+1. Therefore, the perimeter is 41 yards.

A radio transmission tower is 170 feet tall. how long should a guy wire be if it is attached 15 feet from the top and is to make
beks73 [17]
The image of the given scenario is attached below.

A right angled triangle is formed, with one angle equal to 27 degrees. The perpendicular side is 155 and we are to find the length of guy wire which makes the hypotenuse of the right angled triangle.

Using the formula of sine, we can write:

sin(27)= \frac{155}{x}  \\  \\ &#10;x= \frac{155}{sin(27)} \\  \\ &#10;x=341

Rounding to nearest whole number, the length of the guy wire that must be attached is 341 feet.
