The formula for the circumference of a circle is c = 2r, where r is the radius and c is the circumference. the equation solved for r is r = .
find the radius of a circle that has a circumference of 16.

8 units

Step-by-step explanation:

Given: The formula for the circumference of a circle is , where r is the radius and C is the circumference.

To solve equation for r , we divide on both sides, we get

Now, the circumference of the circle =

Then,

Hence, Circumference of the circle = 8 units

step-by-step explanation:

i think you should think about the question and not look online.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
