A circular pool has a radius of 6 ft. What is the approximate circumference of the pool?

A. 19 ft
B. 38 ft
C. 113 ft
D. 452 ft

Answers

Circumference = 2πr;
r = 6 ft. => C = 2π • 6 ≈ 37.7 ≈ 38 ft.
Answer: B 38 ft.

Answer: Option B. 38 ft

Step-by-step explanation:

To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, r represents the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14.

In this problem, we are given that the radius of the circular pool is 6 ft. We can substitute this value into the formula to find the circumference:

C = 2πr

C = 2π(6)

C ≈ 37.7 ft

Therefore, the approximate circumference of the pool is 37.7 feet. This is closest to answer choice B, which is 38 ft.

Step-by-step explanation:

Use PEMDAS

1.Do the parentheses-(These are parentheses) first

When the number it touching another number like this, you need to multiply them together

12x6=72

72+14x2x2

2. Then do exponents, but we don't have any so next to multiplying

2x2=4

72+14x4

14x4=56

3. Now we divide, but we don't have to divide anything so now we add

Firstly, you have to find the area of the whole shape. After that, you subtract that from the area of the individual triangle to get your answer.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2

The area of the entire shape is 42yd^2

Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.

The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.

Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2

The area of the dotted triangle is 6yd^2

Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.

42-6= 36yd^2

Area of shaded region: 36yd^2 (i think)

Step-by-step explanation:

Answer:

4 1/5 or 21/5 (improper fraction)

Step-by-step explanation:

To find the area of a rectangle, there is a formula:
[tex]A=lw[/tex]

So, we know the length is 7ft, and the width is 6/10.

Substitute in the 2 values:

[tex]A=7(6/10)[/tex]

From here, you can go 2 ways:

1) Change 6/10 to a decimal, 0.6

   -Then, multiply 7 x 0.6

   - This equals 4.2, which as a fraction is 4 1/5 or 21/5

2) Turn 7 into a fraction, 7/1 and multiply the numerators and denominators:

  - 7/1 x 6/10 = 42/10 = 21/5

Describe a rule for determining how much the store charges based on the number of turkey subs delivered.

Answers

The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.

For example, if the store charges $5 for each turkey sub, the rule could be:

Total cost = $5 per sub * Number of subs delivered

So if the store delivers 10 turkey subs, the total cost would be:

Total cost = $5 per sub * 10 subs = $50

If the store delivers 20 turkey subs, the total cost would be:

Total cost = $5 per sub * 20 subs = $100

This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.

theta is a right angled triangle tan theta=24/43) work out the value of theta give your answer to 1 decimal place

Answers

Answer:

We know that tan(theta) = opposite/hypotenuse = 24/43.Using inverse tangent, we can find the angle theta:theta = tan^(-1)(24/43)Using a calculator, we can find:theta ≈ 29.6 degrees (rounded to 1 decimal place)Therefore, the value of theta to 1 decimal place is approximately 29.6 degrees.

Step-by-step explanation:

Final answer:

The value of theta in a right angle triangle for which tan(theta) = 24/43 can be found using the inverse tangent function, also known as arctan. When evaluated, theta equals approximately 29.4 degrees.

Explanation:

In trigonometry, the tangent of an angle in a right angle triangle is the ratio of the side opposite to the angle to the side adjacent to the angle. Here, tan(theta) = 24/43, which means the ratio of the opposite side to the adjacent side is 24/43. To find the angle 'theta', you will need to use the inverse tangent function, commonly known as arctan or tan^-1.

In this case, theta = arctan(24/43). Use a calculator and ensure it's set to give the answer in degrees, not radians. The answer would be approximately 29.4 degrees to 1 decimal place.
