The angle subtended at the centre of the circle by a 2.9 centimeter arc is equal to 15° 38.46'/15° 38' 27.6''.
What is the measure of the central angle of a circular section?
In this problem we have to determine the measure of a central angle of a circular section in DMS (Degrees - Minutes - Seconds) system, in which a degree is equal to 60 minutes and a minute to 60 seconds. First, we must calculate the radius of the circle by the area formula:
r = √ (A / π) (1)
r = √ (354 / π)
r ≈ 10.615 cm
Then, the measure of the central angle in radians is found by the equation of circular arc:
θ = s/r
θ = 2.9 cm / 10.615 cm
θ = 0.273 radians
Finally, we convert the angle into DMS system:
θ = 0.273 rad × 180°/π
θ = 15.641°
Degrees: 15°
Minutes and seconds: 0.641° (38.46')
Minutes: 38'
Seconds: (0.46' = 27.6'')
The angle subtended at the centre of the circle by a 2.9 centimeter arc is equal to 15° 38.46'/15° 38' 27.6''.

A right triangle has a leg length of square root of 11 and a hypotenuse length of 9. Determine the length of the other leg of the right triangle.
The length of the other leg of the right triangle is √70. The result is obtained by using the concept of the Pythagoras theorem.
What is the Pythagoras theorem?
The Pythagoras theorem states that the square of the hypotenuse of a right triangle is equal to the squares of the other length sides. It can be expressed as
a² + b² = c²
Where
a = baseb = altitudec = hypotenuse (the longest side)Base altitude is also called as legs of the right triangle.
A right triangle has a leg length of √11 and hypotenuse of 9. Find the length of the other leg!
Let's say
a = √11c = 9The length of other leg is b, the shorter side of hypotenuse.
By using the Pythagoras theorem, we get b.
a² + b² = c²
(√11)² + b² = 9²
11 + b² = 81
b² = 81 - 11
b² = 70
b = √70

8.6 cm2 is the area of a triangle with a base of 4.8 cm and a height of 3.6 cm.
What are triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.
This characteristic is known as the triangle's angle sum property.
If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.
In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.
A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.
The vertex is the intersection of two straight lines. The triangle therefore has three vertices.
According to our question-
Base: 4.8 cm.

How do you find the coordinates of a triangle with midpoints?
To find the coordinates of a triangle with midpoints, you must first calculate the midpoints of each side by averaging the coordinates of the two endpoints.
To find the coordinates of a triangle with midpoints, you first need to calculate the midpoints of each side of the triangle. To do this, take the two endpoints of the side and average their coordinates. For example, if the two endpoints are (x1, y1) and (x2, y2), then the midpoint would be ((x1+x2)/2, (y1+y2)/2). Once you have all the midpoints, you can use the midpoint formula to calculate the coordinates of the triangle. The midpoint formula states that the coordinates of the triangle can be found by taking the average of the midpoints of the three sides.

The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.
The height of the first rectangle is 2 and the area is 6x^{2}. To get to 6x^{2} you have to multiply by 3x^2.

Can an exponential function be 1?
An exponential function can be equal to 1, but it would have to be a special case.
To determine this:
An exponential function has the form f(x) = ab^x, where a and b are constants. For the function to be equal to 1, the output value of the function must be 1 for all values of x. Therefore, we must have:
[tex]ab^x = 1[/tex]
In order for this equation to be true for all values of x, a and b must be chosen such that:
ab = 1
This means that a and b must be reciprocals of each other. For example, if a = 2, then b = 1/2. In this case, the function [tex]f(x) = 2(1/2)^x[/tex] would be equal to 1 for all values of x.
Another example would be if a = 1 and b = 1. In this case, the function [tex]f(x) = 1(1)^x[/tex] would be equal to 1 for all values of x.
It's important to note that while an exponential function can be equal to 1, it would only be in cases where a and b are reciprocals of each other and not with any other values.

What is the solution to this system of linear equations XY 6 and Y x =- 10?
The solution to this system of linear equations y - x = 6 and y + x = -10 is (-8, -2).
y - x = 6
⇒y = x + 6
y + x = -10
⇒y = - x - 10
Since both equations are equal to y, equate them.
x + 6 = - x - 10
x + x = - 10 - 6
2x = - 16
Divide both sides by 2
x = -8
Put the value of x in either of the equations
y - x = 6
y - (-8) = 6

Find the exact volume of the solid. Note that the figure is a half-sphere removed from the cylinder. 25mm 15mm
The exact volume of the solid is 963 2/3π cubic cm
How to determine the exact volume of the solid.From the question, we have the following parameters that can be used in our computation:
Shapes = Half-sphere and cylinder
A half-sphere is called a hemisphere, and the volume is calculated as
V₁ = (2/3)πr³
From the given figure (see attachment), we have
r = 14 cm/2
r = 7 cm
Substitute the known values in the above equation, so, we have the following representation
V₁ = (2/3)π * 7³
V₁ = 686/3π
Next, we have the volume of the cylinder to be
V₂ = πr²h
Where
r = 14 cm/2
r = 7 cm
And
h = 22 - 14/2 = 15
So, we have
V₂ = πr²h
Substitute the known values in the above equation, so, we have the following representation
V₂ = π * 7² * 15
V₂ = 735π
The volume of the solid is then calculated as
V = V₁ + V₂
So, we have
V = 686/3π + 735π
Evaluate the sum
V = 963 2/3π
