Heidi is making a tower using sugar cubes. Each sugar cube has a side length of 1 cm. Each layer has 4 sugar cubes, arranged in

Archy [21]

Answer:

3 layers

Step-by-step explanation:

Given

$L = 1cm$ --- side length of the cube

Each layer = 2 * 2 cube

$Volume = 24cm^3$

Required

Determine the number of layers

First, we calculate the volume of each layer:

The length of the layer is:

$Length = 2 * L$

$Length = 2 * 1cm$

$Length = 2cm$

Next, we calculate the volume of each layer:

$Volume = Length^3$

$Volume = (2cm)^3$

$Volume = 8cm^3$

The number of layer is calculated by dividing the volume of the tower by the volume of each layer

$Layers = \frac{24cm^3}{8cm^3}$

$Layers = 3$

a circular railroad crossing sign has a diameter of 30 inches. which measurment is closest to the area of the sign in square inc

nasty-shy [4]

Answer

$707in^2$

Explanation

The formula to determine the area of a circle is $\pi r^2$

Convert the diameter to radius

30/2 = 15

The radius is 15

Plug in the radius into the formula above

$\pi 15^2 = 225\pi$

225 * $\pi$ = approximately $707in^2$
