The volume of cylinder is 2352π in³ while the volume of cone is 784π in³. The volume of the cylinder is three times the volume of the cone
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A cylinder has radius 14 inches and height 12 inches. A cone has the same radius and height.
Volume of cylinder = π * radius² * height = π * 14² * 12 = 2352π in³
Volume of cone = (1/3) * π * radius² * height = (1/3) * π * 14² * 12 = 784π in³
The volume of the cylinder is three times the volume of the cone.

For the target below an archer randomly shoots an arrow which hits the target, what is the theoretical probability the arrow will hit the small square on the upper left? Assume all squares are the same size. Round to the nearest tenth of a percent.
A. 9.8%
B. 2.5%
C: 1.0%
The theoretical probability that the arrow will hit the small square on the upper left is approximately 9.8%. (Option A)
To determine the theoretical probability, we first need to calculate the areas involved. Let's start by finding the area of the entire circular target. The formula for the area of a circle is given by A = π * r², where 'r' is the radius. Plugging in the given radius (36 inches) into the formula:
A_circle = π * (36 inches)² ≈ 4069.73 square inches.
Next, we need to calculate the area of the small square in the upper left corner. Since the square is positioned at a corner of the circle, it forms a quarter of a circle. The area of this quarter circle can be calculated as follows:
A_quarter_circle = ¼ * A_circle. = ¼ * 4069.73 = 1017.43
Now, let's find the area of the square. The formula for the area of a square is A_square = side², where 'side' is the side length. Plugging in the given side length (5 inches) into the formula:
A_square = (5 inches)² = 25 square inches.
However, there are four identical squares inside the quarter circle, so the total area of all the squares combined is:
Total_Area_squares = 4 * A_square.
Now, to calculate the probability of hitting the small square in the upper left corner, we divide the area of that square by the area of the quarter circle:
Probability = (A_square / A_quarter_circle) * 100. = 25 / 1017.43 * 100 = 9.8%.
Hence the correct option is (a).

Answer: 6
Step-by-step explanation: NOT NEEDED
Find the center and radius of the circle represented by the equation below.
Answer:
Center= (-6,-8)
Radius= 6
Step-by-step explanation:
We use the formula (x-h)^2+(y-k)^2 then plug in our numbers:
[tex](x - h)^2 + (y - k)^2 = r^2\\(x+6)^2 +(y-k)^2=36[/tex]
In the equation -h is 6 so our h (x-coordinate) is -6
In the equation -k is 8 so our k (y-coordinate) is -8
In the equation r^2 is 36 so we take the square root of 36 to get r which is 6.

The angle ∠DEF is equal to 90 degrees. Then the triangle ΔDEF will be a right-angle triangle.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The angle ∠DEG = 51° and angle ∠GEF = 39°.
Then prove that the triangle ΔDEF will be a right-angle triangle. Then we have
We know that if one angle of the triangle is 90 degrees then the triangle will be named a right-angle triangle.
The sum of the angle ∠DEG and ∠GEF will be
∠DEF = ∠DEG + ∠GEF
∠DEF = 51° + 39°
∠DEF = 90°
Then the triangle ΔDEF will be a right-angle triangle.
