7. The volume of a cylinder is represented by the formula V = r² h.
Find each missing height and show your reasoning.
volume (cubic inches) radius (inches) height (inches)
96. 4
31.25. 2.5
V. r
Based on the calculations, each missing height of this cylinder is; 6 and 5 inches.
How to calculate the volume of a cylinder?Mathematically, the volume of a cylinder can be calculated by using this formula:
V = πr²h
Where:
V is the volume of a cylinder. h is the height of a cylinder. r is the radius of a cylinder.
Now h the subject of formula, we have:
h = V/πr²
When V = 96π and r = 4, the volume of this cylinder is;
h = V/πr²
h = 96π/π(4)²
h = 96/16
Height, h = 6.
When V = 31.25π and r = 2.5, then the volume of this cylinder is;
h = V/πr²
h = 31.25π/π(2.5)²
h = 31.25/6.25
Height, h = 5.

“A falcata is formed by taking a quadrant of a circle and removing a semicircle from it (see diagram).If the radius of the original circle is 2 units long, find the exact area of the falcata.”hello!! please help me out! i’m begging. this assignment is kicking my teeth in!!
step 1
Find out the area of the complete quadrant of the circle (1/4 of the complete circle)
[tex]A=\frac{1}{4}*pi*r^2[/tex]where
r=2 units
substitute
[tex]\begin{gathered} A=\frac{1}{4}*pi*2^2 \\ A=pi\text{ unit}^2 \end{gathered}[/tex]step 2
Find out the area of the semicircle removed
[tex]A=\frac{1}{2}*pi*r^2[/tex]where the radius of the semicircle removed is half of the radius of the circle
so
r=2/2=1 unit
[tex]\begin{gathered} A=\frac{1}{2}*pi*1^2 \\ A=\frac{pi}{2}\text{ unit}^2 \end{gathered}[/tex]therefore
to find out the area of the falcata, subtract the area of the removed semicircle from the area of the quadrant of the circle
The area of the falcata is
A=pi-pi/2=pi/2 unit2
the area of the falcata is pi/2 square unitsThe sum of three times x and 4 is 25. Find x.

Data collected over a period of time should be graphed by using apie chart. C
Question 9.
In the construction of a frequency distribution, it is NOT a good idea to have overlaping class limits such as 10-20, 20-30, 30-40.
Let's determine if the above statement is true or false.
A frequency distribution shows a representation of the num ber of observations within a given interval either in tabular or grahical format.
In the construction of a frequency distribution, the class limits should be made very clear in order for each observation to fall into only one class.
It is not a good idea to have ovelaping class limits like 20-30, 30-40. This is because overlaping limits such as this would make it dificult to determine the class where 30 is located.
Therefore, this statement ''it is NOT a good idea to have overlaping class limits such as 10-20, 20-30, 30-40'' is TRUE.

Finding the dimensions of a rectangle given its perimeter and a...
The length of a rectangle is five times its width.
If the perimeter of the rectangle is 120 in, find its length and width.
length: 111
width: in
X
E
S
Answer:
Width = 10 in
Length = 50 in
Step-by-step explanation:
Define the variables
Let x be the width of the rectangle.If the length is five times its width, then the length of the rectangle is 5x.Given the perimeter is 120 in:
[tex]\begin{aligned}\textsf{Perimeter of a rectangle} & = 2(\sf width + length)\\120 & = 2(x + 5x)\\120 & = 2(6x)\\120 & = 12x\\\dfrac{12x}{12}&=\dfrac{120}{12}\\\implies x&=10\end{aligned}[/tex]
Solution:
Width = 10 inLength = 5 × 10 in = 50 inWrite as a monomial in standard form.
The monomial in standard form will be written as 5y³x².
A Monomial may be defined as a type of polynomial which contains only one term. For example, 3x², 5x and 6x are called monomials. When written in standard form it is the product of one or more factors which can be a constant coefficient and one factor for each variable in the expression. While writing in standard form the terms having the highest power is written first and then the succeeding powers are written. Here, the expression given is 5x²y³ which is not in standard form. The terms having highest power is y³ so it should be written before the term x² as 5y³x² which will be the required standard form.

Mary is four years older than Sue. If the sum of their ages is 16, how old are Mary and Sue?
Answer: Mary 10 Sue 6
Step-by-step explanation:
Answer:
Sue is 6 and Mary is 10
Step-by-step explanation:
let Sue's age be x then Mary is x + 4 and the sum of their ages is
x + x + 4 = 16
2x + 4 = 16 ( subtract 4 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
x + 4 = 6 + 4 = 10
then Mary is 10 and Sue is 6

Directions: Determine whether each equation represents a direct variation. If yes, identify the
constant of variation.
Y - 6 =2(x-3)
Answer:
Yes, this equation represents a direct variation equation
constant of variation = 2
=========================================================
Explanation:
Let's solve for y
y - 6 = 2(x-3)
y - 6 = 2x - 6
y - 6+6 = 2x - 6+6
y + 0 = 2x + 0
y = 2x
The equation is in the form y = kx which fits a direct variation equation. The constant of variation is k = 2.
