The formula for the circumference of a circle:
C = 2(π)(r)
To solve for r, just divide both sides by 2π.
C/2π = r
For this problem, you are given the C, so plug that into the equation.
8π = 2(π)(r)
Now to solve for r, just divide both sides by 2π
4 = r
The radius of the circle is 4.
Answer:
Step-by-step explanation:
a) 4/9*x^4
b) 2/y
2x + 5y = -15 is the standard form of equation
<em><u>Solution:</u></em>
Given that,
<em><u>The point slope form of the equation of the line that passes through (-5, -1) and (10, -7) is given by:</u></em>

We have to write the standard form of the equation
The standard form of an equation is Ax + By = C
In this kind of equation, x and y are variables and A, B, and C are integers
<em><u>Let us convert the given equation into standard form</u></em>

Thus the standard form of equation is found
Answer:
a ║ c
b ║ f
Step-by-step explanation:
when parallel lines are cut by a transversal line, the supplementary angles are angles whose angle measure adds up to 180°
so answers are:
a ║ c
b ║ f
(1,2) when plugged into equation so the answer would be C
