Answer:
Pyramid B is 2.6888 times the volume of pyramid A
Step-by-step explanation:
The volume is proportional to the height, and to the square of the linear measure of the base.
Then the ratio of volumes will be ...
B/A = (592²·247)/(492²·133) = 86564608/32194512 ≈ 2.6888
Pyramid B has the greater volume by a factor of about 2.6888.

<em>Additional comment</em>
The actual volumes in cubic meters will be 1/48 of the numbers we used in the ratio above.
If you recall that the side length is related to the perimeter by ...
P = 4s ⇒ s = P/4
and the volume is ...
V = 1/3s²h
Then you have ...
V = 1/3(P/4)²h = 1/48·P²h . . . . . . P²h is the number we used above
Answer:
2x - 2y
Step-by-step explanation:
P = 7x + 2y
P =a + b + c
7x + 2y = 2x + y +3x - 5y + c
7x + 2y - 5x - 4y
= 2x - 2y
Answer:
Equation: 
Solution: 
Step-by-step explanation:
A square is a quadrilateral that has four equal sides and four equal angles that measure 90 degrees (An angle that measures 90 degrees is also known as "Right triangle".
By definition, the perimeter of a square can be calculated by multiplying the length of any of its sides by 4 (because all its sides are congruent, as it was explained before).
In this case, you know that the perimeter of this square is 36 feet.
Then, you can write the following equation to model this situation:

Where "s" is the length of any side of the square.
Then, you need to solve for "s" in order to find its value. Divide both sides of the equation by 4.
You get that it is:

1. First you would multiply 32 times 32
2. multiply 32x4
3. add those
4. do the same for #6
add everything
Answer:
<h2>100πcm².</h2><h2>None of the options is correct</h2>
Step-by-step explanation:
Total surface area of a cone
= 
Since the diagram is half of a cone, its surface area will be 
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m
