Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = = = 0.5, hence
y = 0.5x ← equation of variation
Answer:
B) -x+8y=56
Step-by-step explanation:
y=1/8x+7
Multiply by 8 to clear the fraction
8y = 8(1/8x+7)
Distribute
8y = 8*1/8x +8*7
8y = x+56
Subtract x from each side
-x+8y = x-x+56
-x+8y = 56

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
