The approximate diameter of the circle is 5.73 inches, and the approximate radius is 2.86 inches.
To discover the diameter and radius of a circle with a given circumference, ready to utilize the taking after equations:
Circumference = π * Diameter
Diameter = Circumference / π
Given that the circumference of the circle is 18 inches, able to calculate the diameter as follows:
Diameter = 18 inches / π
To discover the radius, we will utilize the equation:
Radius = Diameter / 2
Let's calculate the values:
Diameter = 18 inches / π ≈ 5.73 inches
Radius = 5.73 inches / 2 ≈ 2.86 inches
Hence, the approximate diameter of the circle is 5.73 inches, and the approximate span is 2.86 inches.

Hello there, to answer your question....
The diameter and radius of a circle with an 18 inch circumference is
I hope the information I have provided helps. :)
Answer:
3x^2 - x - 10 = 0
3x^2 - 6x + 5x - 10 = 0
3x(x - 2) + 5(x - 2) = 0
(3x + 5)(x - 2) = 0
x = -5/3 , 2
Step-by-step explanation:
mark me brainliest please
3x² - x = 10
3x² - x - 10 = 0
Δ = b² - 4.a.c
Δ = -1² - 4 . 3 . -10
Δ = 1 - 4. 3 . -10
Δ = 121
There are 2 real roots.
x = (-b +- √Δ)/2a
x' = (--1 + √121)/2.3
x'' = (--1 - √121)/2.3
x' = 12 / 6
x'' = -10 / 6
x' = 2
x'' = -5/3
Number of amusement parks and arcades in 2004 = 3344
Decrease in the number of amusement parks from 2004 to 2009 = 148
So, the expression to calculate the total number of amusement parks and arcades in 2009 is 3344 - 148
Evaluating the expression we get the total number of amusement parks and arcades in 2009 as 3196
Hope that help!
The two numbers in question obtained by creating a system of equations are 56 and 36
Let the two numbers be : a and b
From (2):
Substitute (3) into (1)
a + b = 92
20 + b + b = 92
20 + 2b = 92
2b = 92 - 20
2b = 72
b = 72/2
b = 36
From (3) :
a = 20 + 36
a = 56
Therefore, the two numbers are 56 and 36
