Answer:</h2>
<h3>Radius:</h3>
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
<h3>Diameter:</h3>
2 times the radius is the circle's diameter.
<h3>Circumference:</h3>
The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

Answer:
n=3
Step-by-step explanation:
64^(1/3)
Note that the exponent 1/3 given stands for the third root of the integer.
64^(1/3) =4
Check: 4 x 4 x 4 = 64
(By comparison of 64^(1/3) to 64^(1/n) means n= 3)
∜(64^(1/3)) =∜(4) = 1.41421356
The real number is
All the roots are:
1.41421356
1.41421356i
−1.41421356
−1.41421356i
4 is not a perfect 4th power.
Answer:
height = 13.75 feet
Step-by-step explanation:
use the Pythagorean theorem
hypotenuse^2 =base^2 + height^2
15^2 = 6^2+height^2
225 = 36 + height^2
189 = height^2
height = 13.75 feet
Answer:
line L is not parallel to AB
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 4 - 2x ( divide terms by 3 )
y = 
- 
x ← in slope- intercept form
with slope m = -
Calculate slope of AB using the slope formula
m = 
with (x₁, y₁ ) = A(1, 3) and (x₂, y₂ ) = B(- 2, - 1)
= 
= 
=
Parallel lines have equal slopes
Since the slopes are not equal then the lines are not parallel
