50.2 in^2
Answer:
50.2 in^2
Step-by-step explanation:
Using the Formula
A=πr2
d=2r
Solving for A
A= 1/4 π d^2 = 1/4*π*8^2 = 50.26548

How were greek city states formed
Answer:
Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place.

Mikhail believes he can use the multiplication expression 1/2 x 6 to find the total number of 1/2 pound servings of rice he can make from 6 pounds of rice. Which statement best explains why Mikhail is correct or incorrect?
A) Mikhail is correct in using a multiplication expression because the product of 6 and 1/2 is an integer.
B) Mikhail is correct in using a multiplication expression because One-half is the number of servings per pound.
C) Mikhail is incorrect in using a multiplication expression because the term “total” implies finding the sum of an addition expression.
D) Mikhail is incorrect in using a multiplication expression because the question asks how many equal-sized parts 6 can be divided into.
Answer: it’s a because
Step-by-step explanation:
The statement best explains why Mikhail is correct is; B) Mikhail is correct in using a multiplication expression because One-half is the number of servings per pound.
WE are given that Mikhail believes he can use the multiplication expression 1/2 x 6 to find the total number of 1/2 pound servings of rice he can make from 6 pounds of rice.
Since one-half pound of rice equals one serving, Mikhail can divide 6 pounds of rice by one-half to find the total number of servings.
Alternatively, Mikhail can use the multiplication expression 1/2 x 6 to find the same answer, which is 3 servings.
Therefore, Mikhail is correct in using a multiplication expression because One-half is the number of servings per pound.

A scarf is a triangle with two perpendicular sides that are the same length. Which two terms describe the triangular scarf? A. isosceles, right B. isosceles, acute C. isosceles, obtuse D. equilateral, acute
Answer:
A triangular scarf is an isosceles right triangle.
Step-by-step explanation:
Given: A scarf is a triangle with two perpendicular sides that are the same length.
We have to name which two terms describe a triangular scarf.
Isosceles triangle is a triangle with length of two of its sides equal.
Right angled triangle is a triangle in which one angle is a right angle.
Given :
The two sides of scarf are perpendicular to each other.
Thus, the angle formed between them is 90°. Hence, right angled triangle.
Also, length of two sides are same, Hence isosceles triangle.
Thus,a triangular scarf is an isosceles right triangle.

What is the value of x in the figure?
Answer:
29
Step-by-step explanation:
Since we know that the x-axis is 180 degrees and the square looking symbol represents that it is 90 degrees, we know that the other side has to also equal 90 degrees since 180-90=90.
To find the x, we need to subtract 90 from 61, which would give us 90-61 = 29.
In the figure, each cube has a volume of 1 cubic unit. Find the volume of the figure and the area of its base.
A rectangular prism is made up of cubes. The length of the prism is 4 units, width is 3 units, and height is 3 units.
Answer:
the volume is 36 and the area of its base is 12
Step-by-step explanation:
volume = 4x3x3 = 36
area of base = 4x3=12 (do not include height)
The area of the base and the volume of the prism are 24 cubic units and 8 square units.
To find the volume of the rectangular prism, you can multiply its length, width, and height together.
In this case, the length is 4 units, the width is 2 units, and the height is 3 units.
Volume = Length x Width x Height
Volume = 4 units x 3 units x 3 units
Volume = 24 cubic units
Therefore, the volume of the rectangular prism is 36 cubic units.
To find the area of the base, you need to consider that the base is a rectangle with a length of 4 units and a width of 3 units.
Area of the Base = Length x Width
Area of the Base = 4 units x 2 units
Area of the Base = 8 square units
Therefore, the area of the base of the rectangular prism is 12 square units.
Hence the area of the base and the volume of the prism are 24 cubic units and 8 square units.

The subject of the formula below is y.
a=4x/t - p
Rearrange the f make x the subject.
Answer:
x = t(a+p)/4
Step-by-step explanation
Given the expression
a=4x/t - p
We are to make x the subject of the formula
a=4x/t - p
Add p to both sides
a+p = 4x/t - p+p
a+p = 4x/t
Cross multiply
t(a+p) = 4x
Rearrange
4x = t(a+p)
Divide both sides by 4
4x/4 = t(a+p)/4
x = t(a+p)/4

Answer:
x = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar triangles, thus the ratio of corresponding sides are equal, that is
[tex]\frac{BD}{BA}[/tex] = [tex]\frac{BE}{BC}[/tex], substitute values
[tex]\frac{x+5}{3x+5}[/tex] = [tex]\frac{4}{7}[/tex] ( cross- multiply )
4(3x + 5) = 7(x + 5) ← distribute parenthesis on both sides )
12x + 20 = 7x + 35 ( subtract 7x from both sides )
5x + 20 = 35 ( subtract 20 from both sides )
5x = 15 ( divide both sides by 5 )
x = 3
