Please mark as Brainliest! :)
Have a nice day.
Final answer:
The circumference of the circle is approximately 18.84 kilometers.
Explanation:
The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle.
In this case, the radius of the circle is given as 3 kilometers.
So, the circumference of the circle is C = 2π(3) = 6π kilometers.
To find a numerical approximation for π, we can use the value 3.14.
Therefore, the circumference of the circle is approximately C = 6(3.14) = 18.84 kilometers. This calculation demonstrates a practical method to assess the distance around a circle based on its radius, providing a tangible measurement for the circle's outer boundary in a real-world context.

I need help! Please answer below on card A
Answer:
x = 8
DBC = 32
Step-by-step explanation:
The sum of the two smaller angles is the larger angle
23+4x = 55
Subtract 23 from each side
23+4x-23 =55-23
4x = 32
Divide each side by 4
4x/4 = 32/4
x = 8
Then we want to find DBC = 4x = 4*8 = 32

In order for the points to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 5 + 6 = 11 > 2, 5 + 2 = 7 > 6, and 6 + 2 = 8 > 5. Therefore, the points form a triangle.
Jake buys apples buy the pound and they are 24 pounds in one case. Jake wants to order 480 pounds of apples so how may cases does he have to order
Answer:
20
Step-by-step explanation:
24 pounds per case, and Jake wants 480 pounds.
480 ÷ 24 = 20 cases.
how many different outcomes are possible from rolling a six sided cube four times
Answer:
1296 different outcomes
Step-by-step explanation:
Each cube has 6 possible values (from 1 to 6), and for each additional cube rolled, we have 6 more possible values, and the final number of different outcomes is the product of all the number of possible values for each cube.
So, if we roll the cube four times, the total number of different outcomes is:
6 * 6 * 6 * 6 = 1296
We have 1296 different outcomes from rolling the six sided cube four times.
The length of a rectangle is (X + 8) and the width is (x - 3). Find the dimensions of the rectangle if the area is 42 square inches.
Answer:
Length = 14 inches
Width = 3 inches
Step-by-step explanation:
length * width = area
(x + 8 ) (x - 3) = 42
Use FOIL method
x*x - x*3 + 8*x - 8*3 = 42
x² -3x + 8x - 24 = 42
x² + 5x - 24 - 42 = 0
x² + 5x - 66 = 0
Sum = 5
Product = 66
Factors = 11 , (-6)
x² + 5x -66 = 0
x² + 11x - 6x - 6*11 =0
x(x + 11) - 6(x + 11) = 0
(x + 11) (x -6) = 0
x + 11 is ignored because length and width will not have negative value.
x - 6 = 0
x = 6
Length = x + 8 = 6 + 8 = 14 inches
Width = x - 3 = 6 - 3 = 3 inches
Below is the graph of a trigonometric function. It intersects its midline at (-1/2pi,3.3), and it has a
maximum point at (-2pi,9.8).
What is the amplitude of the function? Please show me how to do it too so I can do the rest of the problems
Answer: amplitude = 6.5
Step-by-step explanation:
The amplitude of a function is the maximum displacement from the from a fixed point or from the origin.
From the graph, you take the initial position of the object from the broken red line which is equal to 3.3 at the Y axis.
The peak or the maximum value = 9.8
Amplitude = 9.8 - 3.3 = 6.5
The maximum displacement is at Y axis

In a right triangle, 0 is an acute angle and cos0= 6/11. Evaluate the other five trigonometric functions of 0.
Answer:
sin O = √85/11, csc O = 11/√85
cos O = 6/11, sec O = 11/6
tan O = √85/6, cot = 6/√85.
Step-by-step explanation:
cos = adjacent / hypotenuse = 6/11, so the opposite side to angle O
= √(11^2 - 6^2)
= √85.
csc O = 1/sin O
sec O = 1/cos O
cot O = 1/tan O.

What is the equation that represents the line?
Answer: -7-4
Step-by-step explanation:
In the above triangle, which angle has the largest measure?
Answer:
Angle A
Step-by-step explanation:
Angle A is the opposite angle to the longest side of the triangle.
Because the angle is larger, the side opposite of it should be long enough to connect to the two other sides.
