The circumference of a circle is
9.42 cm. Determine the radius(r)
given the equation for
circumference is, C =2??r
Answer:
1.5 cm
Step-by-step explanation:
1. To find the radius, we use the equation [tex]r = \frac{C}{2\pi}[/tex]
2. Now, we plug in the values and simplify to get the radius. In this case, we'll use pi as 3.14.
[tex]r = \frac{9.42}{2*3.14}[/tex] [tex]r = \frac{9.42}{6.28}[/tex] [tex]r = 1.5[/tex]Therefore, the radius is 1.5 cm.

Evaluate (16+a)+ 6b divided by 3 when a = 2 and b = 3
Answer: 24
Step-by-step explanation:
Follow PEMDAS. Parentheses: 16+a, which is 18. There are no exponents so move on to multiplication. 6b. B is equal to 3, and 6x3 is 18. Next, division. 18/3 is 6. Now do addition so add together 18+6 which is 24.
54 ÷ ( 8 - 5 )
full explanation too please
Use order of operations.
First step do inside the parentheses
8-5 = 3
Now you have 54 / 3
Now divide
54/3 = 18
answer: 18
Answer:
18
Step-by-step explanation:
PEMDAS
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
If the expression contains parentheses, always solve what's in them first
then if there are exponents, solve them
then do any multiplication or division, from left to right
last, do any additon or subtraction, from left to right
In this problem all we have to do is subtract 8 and 5 to get 3 and then divide that into 54 to get 18

What is the area of the blue shaded figure if A=3 cm and B=5 cm?
Use 3.14 to approximate π.
The area of the blue shaded figure will be 47.9 cm².
What is Circle?
Circle is a two dimensional figure in which the set of all the points is equidistance from the center.
Given that;
In the figure,
A = 3 cm
B = 5 cm
Since, The area of a circle = πr²
So, For radius of small circle with radius 3 cm,
Area = πr²
Area = 3.14 × 3²
Area = 3.14 × 9
Area = 30.6 cm²
Hence, Area of small circle = 30.6 cm²
And, Area of the big circle with radius 5 cm,
Area = πr²
Area = 3.14 × 5²
Area = 3.14 × 25
Area = 78.5 cm²
Hence, Area of big circle with radius 5 cm = 78.5 cm²
So, The area of blue shaded circle = 78.5 - 30.6
= 47.9 cm²
Thus, The area of the blue shaded figure will be 47.9 cm².

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
A parallelogram is shown in figure with two diagonals.
We know that;
In a parallelogram, both diagonal intersect at midpoint of each diagonal,
So, We can formulate;
⇒ 2z + 7 = z + 9
Solve for z as;
⇒ 2z - z = 9 - 7
⇒ z = 2
And,
⇒ 3y - 5 = y + 5
⇒ 3y - y = 5 + 5
⇒ 2y = 10
⇒ y = 5
Thus, The value of z = 2
The value of y = 5

Please help my homework I still struggle
Answer:
[tex]x[/tex] = 12
Step-by-step explanation:
The shape ABCDEF is an irregular polygon.
The sum of the interior angles of any regular or irregular polygon = (n - 2) x 180 (where n is the number of sides of the polygon).
Therefore, the sum of the interior angles of shape ABCDEF = (6 - 2) x 180 = 720°
So to find the value of [tex]x[/tex], we need to add together all the interior angles and equal it to 720, then solve for [tex]x[/tex].
Before we do that, we need to determine angle F.
From inspection, we can see that angle F and 52° are a linear pair. We know that a linear pair of angles add up to 180°, so F + 52 = 180 ⇒ F = 180 - 52 = 128°
Therefore:
A + B + C + D + E + F = 720
(10[tex]x[/tex] - 5) + 108 + (8[tex]x[/tex] - 3) + (14[tex]x[/tex] - 25) + 133 + 128 = 720
Collect like terms:
10[tex]x[/tex] + 8[tex]x[/tex] + 14[tex]x[/tex] - 5 + 108 - 3 - 25 + 133 + 128 = 720
Combine like terms:
32[tex]x[/tex] + 336 = 720
Subtract 336 from both sides:
32[tex]x[/tex] = 384
Divide both sides by 32:
[tex]x[/tex] = 12
