what is the diameter of a circle with a circumference of 132ft ? Use 22/7 for pie
Answer:
Step-by-step explanation:
The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.
Given that the circumference is 132ft and π is 22/7, we can write:
132 = (22/7)d
To solve for d, we can multiply both sides by 7/22:
132 × 7/22 = d
Simplifying the left side:
42 = d
Therefore, the diameter of the circle is 42 feet.
Answer:
D = 42
Step-by-step explanation:
Formula to find Diameter = [tex]\frac{C}{\pi }[/tex]
D = 132 ÷ [tex]\frac{22}{7}[/tex]
[tex]D = \frac{132}{1}[/tex] × [tex]\frac{7}{22}[/tex]
132 divide 22 = 6
D = 6 × 7

What is the tax on a $40 purchase if sales tax is 5%?
Answer:
Before Tax Price: $40.00
Sale Tax: 5.00% or $2.00
After Tax Price: $42.00
Step-by-step explanation:
Answer:
42 dollars
Step-by-step explanation:
When doing tax problems, we need to memorize the formula of:
price + tax • price = price with sales tax.
This formula works because you have the initial percentage of the cost, with the added tax, which gives the extra value--then added together it gives the sales cost price.
So let's plug our numbers in
40 + (0.05 or 5%) • 40 = price with sales tax
40 + 2 = price with sales tax
42 = price with sales tax

In a survey of 3,100 people who owned a certain type of car, 1,705 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
55.0% of the people surveyed were satisfied with the car.
What is percentage, how to solve it?We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.
Formula for percentages is (Value/Total value) x 100.
If two values are presented to us, we must determine the percentage difference between them.
Given that, 1,705 said they would buy that type of car again.
Thus, to find people who were satisfied with the car:
Percentage = (Number of satisfied people / Total number of people) x 100%
Percentage = (1,705 / 3,100) x 100% = 55.0%
Hence, 55.0% of the people surveyed were satisfied with the car.

Find the value of x
Answer:
x = 13
Step-by-step explanation:
We know that 5x, x+12, and 90 makes a straight line, which is 180 degrees
5x + x+12 + 90 = 180
Combine like terms.
6x+102=180
Subtract 102 from each side.
6x+102-102=180-102
6x = 78
Divide each side by 6
6x/6 = 78/6
x = 13
Answer:
x = 13
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
We know that,
→ The angle of right angle is 90°.
Forming the equation,
→ (x + 12)° + (5x)° = 90°
Then the value of x will be,
→ (x + 12)° + (5x)° = 90°
→ x + 12 + 5x = 90
→ (x + 5x) + 12 = 90
→ 6x + 12 = 90
→ 6x = 90 - 12
→ 6x = 78
→ x = 78 ÷ 6
→ [ x = 13 ]
Hence, the value of x is 13.

Rounding to the nearest cubic foot, the volume of water that will be in the pool when it is filled is approximately 2713 feet³.
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The first step is to find the radius of the cylinder.
Since the diameter is given as 24 feet, the radius is half of the diameter or 12 feet.
Next, we can use the formula for the volume of a cylinder -
V = πr²h
where V is the volume, r is the radius, and h is the height.
Substituting the given values, we get -
V = π(12)²(6)
= π(144)(6)

In response to the query, we have that The Pythagorean identity for theta = 30° is therefore confirmed since sin(30°) + cos(30°) = 1.
what is Pythagorean theorem?The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.
This trigonometric identity is valid for all theta values. Because it is connected to the geometry-related Pythagorean theorem, it is known as the Pythagorean identity.
According to Pythagorean theory,
[tex]Cos(theta)^2 + Sin(theta^)2 = 1[/tex]
So, you can easily include that value into the equation and simplify it if you need to assess sin(theta) + cos(theta) for a certain value of theta:
[tex]Cos(theta)2 + Sin(theta)2 = 1\\Sin(2) + Cos(30)\\If theta = 30, then 2(30) = 1.\\(1/2)\\c^2 + (√3/2)\\c^2 = 1 \s1/4 + 3/4 = 1 \s1 = 1[/tex]
