Volume of a boxThe formula for measuring the volume of a rectangular box is expressed as:
V = lwh
l is the length
w is the width
h is the height
Given the following
l = 2in
w = 3in
h = 2in
Substitute
V = 2* 3 * 2
V = 12 cubic inches
Hence the volume of the rectangular box is 12 cubic inches

In this assignment, you will explore how the volume is changed when you adjust the height or radius of a cylinder. You will drag points of reference on an interactive tool to represent various changes. The interactive will display the changed volume visually and in the calculations and dimensions. You will then use what you see happening to answer questions.
Answers
The volume of a cylinder changes when you adjust the height or radius as the volume either increases or reduces.
How to illustrate the volume?Let's assume that the height and radius are 14cm and 7cm. The volume will be:
= πr²h
= 3.14 × 7² × 14
= 2154.04cm³
When the radius and height are reduced to 5cm and 9cm, the volume will be:
= πr²h
= 3.14 × 5² × 9
= 706.5cm³
This illustrates that the volume reduces when the height and radius reduces.

A triangle has vertices as D(4,5), E(1,8) and F (1,2). Show that the height from D is also the median from D.
Answers
The x-coordinate of the altitude on EF is the same as the point D(4, 5) and by calculation, the height from D (1, 5) is also median from D (1, 5)
How can the height and median be calculated?The height from D is perpendicular to EF
The slope of EF = (8 - 2)/(1 - 1) = ∞
Therefore, the side EF is parallel to the y-axis.
Therefore, the coordinates of the point of intersection of the altitude from D and the line EF is (1, 5)
The median is the midpoint of the side EF
The coordinates of the midpoint is found as follows;

What is the measure of the corresponding central angle for XY in radians?

Step-by-step explanation:
Arc Length (Radians) = rθ
Given Arc Length XY = 40cm and radius, r = 10cm,
we will substitute these 2 values into the formula to find θ.
(10)θ = 40
θ = 40 / 10
= 4 radians
Answer:
A
Step-by-step explanation:
the length of arc XY is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{0}{2\pi }[/tex] ( r is radius and Θ is central angle )
here arc = 40 and r = 10 , then
2π × 10 ×[tex]\frac{0}{2\pi }[/tex] = 40
20π × [tex]\frac{0}{2\pi }[/tex] = 40 ( cancel 20π and 2π by 2π )

The value of x is 126.87° and the value of y is 53°.
What is an obtuse and an acute angle?An obtuse angle is an angle that is greater than 90° but lesser than 180° while an acute angle is an angle between 0-90°.
From the given information:
sin x° = 0.8
x = sin⁻¹ (0.8)
x = 53.13°

Solve the following linear system by elimination. Check your solution:
1. x + 5y =4
2. 4x + 12y = 8
Answers
Answer:
(- 1, 1 )
Step-by-step explanation:
x + 5y = 4 → (1)
4x + 12y = 8 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate x
- 4x - 20y = - 16 → (3)
add (2) and (3) term by term to eliminate x
0 - 8y = - 8
- 8y = - 8 ( divide both sides by - 8 )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (1)
x + 5(1) = 4
x + 5 = 4 ( subtract 5 from both sides )
x = - 1
As a check
substitute these values into the left side of both equations and if equal to the right side then they are the solution.
- 1 + 5(1) = - 1 + 5 = 4 = right side
4(- 1) + 12(1) = - 4 + 12 = 8 = right side
(- 1, 1 ) is the solution to the system of equations

____
Answers
Answer:
3 < x < 13
Step-by-step explanation:
Triangle Inequality Theorem
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Let x be the length of the unknown side.
Therefore, x will either be the longest side or one of the shorter sides.
Therefore:
x < 5 + 8
⇒ x < 13
And:
8 < 5 + x
⇒ 3 < x
So the range of possible values of the third side is greater than 3 and less than 13: 3 < x < 13
