How does the volume of a cone change when the radius is quadrupled and the height id reduced to 1/5 of the original size?

Mathematics

The volume (V) of the cone is one-third of the product of its height (h) and area (A). 
                                    V = A x h = πr²h 
Now, if the radius is quadrupled and the height is reduced to 1/5, the equation will be,
                                  V2 = π(4r)²(1/5 h) = π(3.2)r²h
Thus, the second volume would be 3.2 time the first volume.

Rom4ik [11]

Answer:

P = \¼R

Step-by-step explanation:

Given

Shape: Rectangle

Division = 4 parts

Required

How much is one part of the division

Represent the rectangle with R and the parts with P

When a rectangle (R) is divided into 4 parts (P); the relationship between R and P is:

P = \frac{R}{4}

P = \¼R

<em>This implies that the one part of the division is ¼ of the divided rectangle</em>

What is the first term of the sequence below? ___1, 5,25,125
gtnhenbr [62]

Answer:

The first term of the sequence is 1/5

Step-by-step explanation:

The first term is 1/5.

The reason is that there is a common ratio between each term. In this case multiplying the previous term in the sequence by 5 would give the next term.

So in this case 1/5 is the first term.

If we multiply 1/5 by 5, it will give the next term which is 1.

1/5*5=1

Thus the first term in the sequence = 1/5....
