The formula to calculate circumference is πd or 2πr. We also know that 2r = d.
So, using these formulas, let's try to figure out the first row of the table.
The diameter is 14.
We know that 2r = d or 2r = 14, therefore r=7. This means the radius is 7.
The circumference is πd or 14π or ≈ 43.96.
Let's move to the second row.
We know that the radius is 21.
2r = d
2(21) = d
d = 42
The diameter is 42.
Therefore, the circumference is 42π or ≈ 131.88
Let's move to the final row.
We know that the radius is 10.5.
2r = d
2(10.5) = d
d=21
Therefore, the diameter is 21 cm.
Circumference = πd = 21π or ≈ 65.94
Answer:
The standard for of the equation would be 5x + 6y = -16
Step-by-step explanation:
To start, we simply need to solve for the constant.
y + 1 = 5/6(x - 2)
y + 1 = 5/6x - 5/3
5/6x + y + 1 = -5/3
5/6x + y = -8/3
Now we need to multiply all the numbers by the largest denominator. This will make all the numbers integers. In this case, that number would be 6.
5x + 6y = -16
