Find Diameter :
---------------------------------------------
Circumference = πD
πD = 12π
D = 12
---------------------------------------------
Find Radius :
---------------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2
Radius = 6
---------------------------------------------
Find Area :
---------------------------------------------
Area = πr²
Area = π(6)²
Area = 36π or 113.10 units² (nearest hundredth)
---------------------------------------------
Answer: Area = 113.10 unit²
---------------------------------------------
A direct variation equation is in the form y = kx. So if you solve this equation will you get it in that form? No you will get y = 16/x. This is an inverse variation.
Answer:
y = -2/3x-9
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2/3x+b
We have a point we can substitute into the line
-5 = -2/3(-6)+b
Subtract 4 from each side
-5-4 =4+b-4
-9 =b
y = -2/3x-9
i wish that i could help you but I just dont understand it... I am sorry
