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

A map of the world has a perimeter of 24 feet. It’s area is 32 square feet. What are the dimensions of the map?
mojhsa [17]

The dimensions of the map are 8 feet × 4 feet

Step-by-step explanation:

Step 1; It is given that the perimeter of the map is 24 feet while the area is 32 square feet. The map is in the shape of a rectangle so we need to calculate its length and its width of this rectangle. The area of any particular rectangle is given by the multiplication of its length with width. The perimeter is given by double the value of the sum of its length and width.

Step 2; Equating these we get

Perimeter = 2 (l + w) = 24 feet

Area = l × w = 32 feet.

From the perimeter formula, (l + w) = \frac{24}{2} = 12

So we have (l + w) = 12 while l × w = 32.

Step 3; Possible values of l and w are

(1 ,11), (2, 10), (3, 9), (4, 8), (5, 7), (6, 6), (7, 5), (8, 4), (9, 3), (10, 2) and (11, 1).

Out of these possibilities only (4, 8) and (8, 4) give a product of 32 but since l is greater than w we have the value of l as 8 feet while w is 4 feet.
