Answer:
The circumference is similar to the perimeter in that it is the total length needed to draw the circle.
We note the circumference as c.
c = 2πr
or
c = πd
This depends on whether or not you know the radius (r) or the diameter (d)
Let’s calculate one manually, for example.
If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.

What does a=? b=? Angle B=?
Answer:
If you were solving the right triangle, it would be:
m∠A = 46°
m∠B = 44°
m∠C = 90°
AB = 32
BC ≈ 23
AC ≈ 24
Step-by-step explanation:
To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:
m∠A = 46° (given)
m∠B = x
m∠C = 90° (given)
180 - (46 + 90) = x
180 - 136 = x
44 = x
m∠B = 44°
To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.
Recall that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
So:
sin46 = BC/32
BC = 32 (sin46)
BC ≈ 23
tan46 = BC/AC
AC = BC/tan46
AC = (23.01887361...) (tan46)
AC ≈ 24

:
4a2 - b2
Simplify ————————
2a - b
Trying to factor as a Difference of Squares:
2.1 Factoring: 4a2 - b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + b) • (2a - b)
Canceling Out :
2.2 Cancel out (2a - b) which appears on both sides of the fraction line.
Final result :
2a + b

Step-by-step explanation:
find the value of x in the angle
Answer:
The answer would be B
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

A 45-45-90 triangle has a leg of length 5.38. What is the length of the other leg?
Answer:
5.38 units
Step-by-step explanation:
Because of the base angle theorem converse, This triangle is an isosceles triangle.
Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units
You may be asking, how do I know it's the other leg that's congruent.
Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.
Let me know if you have any questions.

How to find the area of a parallelogram with 3 numbers?
14.8 square feet is the area of the given parallelogram.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
The area of a parallelogram is given by the formula:
Area = base x height
where the base is the distance between two parallel sides of the parallelogram.
In this case, the height is given as 2 feet, but we need to find the base.
Since the parallelogram has two pairs of parallel sides, we can use the width of 7.4 feet as the base.
Therefore, the area of the parallelogram can be calculated as:
Area = base x height = 7.4 ft x 2 ft = 14.8 square feet
So, the area of the parallelogram is 14.8 square feet.
