Answer:

C = pi * d

Step-by-step explanation:

C = 2 * pi *r

We can replace 2 * r with d since the diameter is twice the radius

C = pi * 2*r

C = pi * d

Complete the equation of the line through (6,-6) and (8,8)
melomori [17]
General formula to determine the equation of the line
y - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope

Find the slope
Given:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)

We could find the slope by using this formula
m = \dfrac{ y_{2} -y_{1} }{ x_{2} -x_{1} }

Plug in the numbers
m = \dfrac{ y_{2} -y_{1} }{ x_{2} -x_{1} }
m = \dfrac{8-(-6)}{8-6}
m = \dfrac{14}{ 2 }
m = 7
The slope is 7

Determine the line equation
Plug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
