Step-by-step explanation:
Formula of the Volume of a Sphere: [tex]\frac{4}{3} \pi r^{2}[/tex]
V = [tex]\frac{4}{3}[/tex] × (3.5)²π
V = [tex]\frac{4}{3}[/tex] × 12.25π
V ≈ 16.333 in³

52°
Step-by-step explanation:
180-112=68
120-68=52
The size of the angle marked x is 52°.
Given that a hexagon and parallelogram share the same one vertex and the angle of the parallelogram is 112°
To determine the size of the angle marked x by utilizing the properties of a regular hexagon and the given angle of 112°.
A regular hexagon has interior angles measuring 120° each. Since the hexagon is regular, all six interior angles are congruent. We can divide the hexagon into six equal triangles, each having an angle of 120°.
In parallelogram, the opposite angles are congruent and the sum of adjacent angles is 180°.
The parallelogram adjacent to the hexagon shares the same vertex as the hexagon's interior angle.
Let the angle adjacent to 112° in parallelogram be a and a is adjacent to angle x in hexagon,
By using parallelogram property gives,
a + 112° = 180°
Subtract 112° from both the sides, gives,
a = 68°
x and a form one angle of the hexagon which is equal to 120° gives,
x + a = 120°
Substitute the value of a = 68° in the above equation
x+ 68° = 120°
Subtract 68° from both the sides, gives,
x = 52°
Hence, the size of the angle marked x is 52°.

can someone please help me find the area of a regular pentagon of radius 4m? thank you :(
Answers
Answer:38.07
Step-by-step explanation:
If you don't have the apothem value, you will need more information to find the area accurately. The radius alone does not provide enough information to find the area of the regular pentagon.
To find the area of a regular pentagon with a given radius, we need to know the apothem (the distance from the center of the pentagon to the midpoint of one of its sides) in addition to the radius. However, you mentioned only the radius, and it is not sufficient to directly find the area.
If you have the apothem value, you can use the following formula to calculate the area of a regular pentagon:
Area = (5/4) * apothem * side length

expression that is equivalent to 7 3/4 + 3 5/6 - 1 3/4 that uses addition instead of subtraction.
Answers
Answer:
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6
Step-by-step explanation:
we do not want the minus sign.
7 3/4 + 1 3/4 - 3 5/6 = 7 3/4 + 1 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7+ 3/4 + 1 + 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7 + 1 - 3 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 5 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6

2. How are the solutions to the inequality -2x ≥ 10 different from the solutions to
-2x > 10? Explain your reasoning.
Answers
9514 1404 393
Answer:
-5 is included in the solution set of the first, but not the second
Step-by-step explanation:
The solution to -2 ≥ 10 is x ≤ -5. The solution to -2x > 10 is x < -5. The difference is that x = -5 is included in the solution set of the first inequality, but is not included in the solution set of the second inequality.
When plotted on a number line, the former inequality has a solid dot at -5, indicating that point is included. The latter inequality has an open dot (circle) at -5, indicating that point is not included. (Both plots are shaded to the left of the dot.)

Find the measure of the exterior angle.
Answers
Answer:
Option (C)
Step-by-step explanation:
By the property of an exterior angle,
Exterior angle of a triangle is equal to the sum of two opposite interior angles.
(15x + 34)° = 29° + (12x + 26)°
15x + 34 = 29 + 12x + 26
15x - 12x = 55 - 34
3x = 21
x = 7
Measure of exterior angle = (15x + 34)°
= 15(7) + 34
= 105 + 34
= 139°
Option (C) is the answer.
