Answer:

<h2><em><u>16</u></em></h2>

Step-by-step explanation:

<h3><em><u>Question</u></em><em><u>:</u></em></h3>

4 × 2(a - 1)

<h3><em><u>Given</u></em><em><u> </u></em><em><u>value</u></em><em><u>:</u></em></h3>

a = 3

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

4 × 2(a - 1)

= 4 × 2(3 - 1) <em>[</em><em>Substituting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>=</em><em> </em><em>3</em><em>]</em>

= 4 × 2(2)

= 4 × 4

= 16

<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>16</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>required</u></em><em><u> </u></em><em><u>answer</u></em><em><u>.</u></em>

Pyramid A has height 5 1/2, and Pyramid B has height 2 3/4. A and B are similar. What is the ratio of their:
N76 [4]

Answer:

Lateral areas have ratio of 4:1

Volumes have ratio of 8:1

Step-by-step explanation:

There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of a:b, the ratio of any surface area type measure is always a^2:b^2 this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of a^3:b^3\\.

Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of \frac{5\frac{1}{2} }{2\frac{3}{4} } which if you simplify it, it is \frac{5.5}{2.75}, which is 2. The ratio of the heights are 2:1.

Now we can apply those rules to this ratio, the ratio of lateral areas would then be 2^2:1^2, which is 4:1. the ratio of volumes would be 2^3:1^3, which is 8:1
