Note: This question needs practical measurements so I am going to use my clock at home. Otherwise, you can measure the clock at your house and work out.
the diameter of the clock= 30 cm
the radius of the clock= 15 cm
(a) the area of the clock is
[tex]\pi r^{2} = 3.14 \times 15^{2} = 706.5 \: cm^{2} [/tex]
(b) The length of the minute hand covered in one hour is equal to the circumference of the clock.
The circumference of the clock is
[tex]2\pi \times radius = 2 \times 3.14 \times 15 = 94.2 \: cm[/tex]

A cylinder has a height of 17 millimeters and a radius of 6 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answers
Answer:
1921.68mm^3
Step-by-step explanation:
Given data
H=17 millimeters
R=6 millimeters.
We know that the expression for the volume of cylinder is
V= πr^2h
substitute
V= 3.14*6^2*17
V= 3.14*36*17
V= 1921.68 mm^3
Hence the volume is 1921.68mm^3

Item 19 The staircase has three parallelogram-shaped panels that are the same size. The horizontal distance between each panel is 4.25 inches. What is the area of one panel?
Answers
Answer:
[tex]Area = 287\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 20.5[/tex]
[tex]Space = 4.25[/tex]
[tex]Panels = 3[/tex]
See attachment
Required
The area of one panel
From the attachment, the total width is 50.5in.
i.e.
[tex]Total\ Width = 50.5[/tex]
Given that there are 2 spaces between the 3 panels and each space has a length of 4.25 in.
The reduced width is:
[tex]Reduced\ Width = 50.5 - 2 * 4.25[/tex]
[tex]Reduced\ Width = 42[/tex]
At this point, we can calculate the width of one panel by dividing the reduced width by the number of panels (3).
[tex]Width = \frac{42}{3}[/tex]
[tex]Width = 14[/tex]
The area of one is:
[tex]Area = Length * Width[/tex]
[tex]Area = 20.5 * 14[/tex]
[tex]Area = 287\ in^2[/tex]

5. A cook needs 10 pounds of flour. He wants to spend the least amount of money. A 2-
pound bag costs $1.59 and a 5-pound bag costs $2.89, which should he buy in order to spend
less money? *
Answers
Answer:
He should buy two of the 5-pound bag.
Step-by-step explanation:
The cook needs 10 pounds of flour.
He wants to spend the least amount of money.
First option is a 5-pound bag for $2.89 each.
He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78
Second option is a 2-pound bag for $1.59 each.
He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.
Second option is $2.17 costlier than the first option.
So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.

A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{400-100}{20-0}(x-0)\\\\y-100=15x\\\\y=15x + 100[/tex]
b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.
